+     JATS Version 1.1                (DAL/BTU) v1.1  (2015-12-15)
+
+     JATS is a continuing maintenance NISO Standard, which
+     requires voting by the ANSI and NISO memberships to be changed. 
+     JATS 1.1 was approved in late 2015, and BITS modified to use
+     the most recent version. No other changes to BITS were made.
+ 
+ 12. BITS remained version "2.0" but becomes "v2.0 20151225"
+     JATS became version "1.1" and "v1.1 20151215"
+

+     BITS Version 2.0                (DAL/BTU) v2.0    (2015-03-15)
+     JATS Version 1.1                (DAL/BTU) v1.1    (2015-03-01)
+
+     BITS was modified, based on user feedback collected in 2014 
+     and January/February 2015, according to the decisions
+     made by the BITS Working Group. This DTD represents current 
+     BITS and an interim version of the non-normative JATS DTD 
+     Suite (version 1.1), as an indication to JATS users of 
+     the decisions that have been made by the JATS Standing
+     Committee. 
+
+     NISO JATS is a continuing maintenance NISO Standard, which
+     requires voting by the NISO membership to be changed. This
+     Committee Draft 1.1 will be sent to the NISO voting
+     membership, to become (if approved) NISO JATS 1.1.
+
+ 11. TITLE/SUBTITLE/ALT-TIT/E ETC. - Some of the question/answer
+     components could take subtitles and alt-titles as well as titles,
+     but all could not. Regularized them to include all title
+     types if a title was possible.
+
+ 10. EXPLANATION - was given a new section-level model similar
+     to that for <answer>.
+
+  9. ANSWER-SPECIFIC PARAGRAPH-LEVEL OBJECTS
+     Created a new PE (answer-para-level) to prohibit 
+     <explanation> at the paragraph level inside
+     <answer>, because that created DTD determinism problems.
+     Rewrote <answer> model to use this PE.
+
+  8. QUESTION MODEL - changed the model for <question> to:
+      - call all the components of sec-opt-title-model
+        rather than calling the grouping PE
+      - Add new element <option>, which is used for multiple 
+        choice questions (instead of <answer>) 
+
+  7. ANSWER/QUESTION ATTRIBUTES
+      - Removed @correct (yes | no) from <answer> and from
+        <answer-set>, because, by definition, an <answer> 
+        is correct. The <option> element may now be marked 
+        with a @correct attribute ('yes' or 'no').
+      -Removed @answer-type from <answer>, since this is 
+       really about the question, not the answer.
+     - Added new attribute @question-response-type to
+       <question>, which takes the old values for @answer-type
+       (multiple choice, short answer, essay, etc.) 
+
+  6. XML:LANG ATTRIBUTE - Added @xml:lang to the attributes lists
+     of <question-wrap> and <question-wrap-group>. 
+
+  5. EXPLANATION - Added @rid to <explanation> since these can
+     now float in the text as answers can. 
+
+  4. QUESTION-PREAMBLE - Added new element to hold setup/
+     preamble information, when the setup is shared by several 
+     questions, for example, a diagram is shown and the questions
+     are similar to "What is angle a?". This preamble is part of
+     a <question-wrap-group> that contains the preamble/setup 
+     (<question-preamble>) and several questions
+     (<question-wrap>).
+
+  3. QUESTION-WRAP-GROUP - Added new element <question-wrap-group>
+     to hold a question setup/preamble (<question-preamble>)
+     and two or more <question-wrap>s based on that preamble.
+
+  2. BITS became version "2.0" and   "v2.0 20150630"
+     JATS became version "1.1" and "v1.1 20150301"

+                                  (DAL/BTU) v1.3 (2021-06-10)
+    
+     ANSI NISO JATS is a continuing maintenance NISO Standard, 
+     which requires voting by both the NISO and ANSI memberships 
+     to be changed. This version of the NISO JATS was approved 
+     by ANSI vote on June 10, 2021, so it supersedes all Committee 
+     Drafts as well as the draft version JATS 1.3 2021 (the version
+     submitted for vote), becoming NISO JATS v1.3 20210610 
+     (ANSI/NISO Z39.96-2019).
+
+     The file names and formal public identifiers have been 
+     changed in the modules and the catalogs.
+
+ 55. JATS 'v1.3d2 20201130' becomes 'v1.3 20210610'

+                                   (DAL/BTU) v1.3d2 (2020-11-30)

+     ANSI NISO JATS is a continuing maintenance NISO Standard, 
+     which requires voting by the NISO and ANSI memberships 
+     to be changed. 
+      
+     This draft DTD represents an interim version of the
+     non-normative JATS DTD Suite, as an indication to JATS users
+     of the decisions that have been made by the JATS Standing
+     Committee. This draft has not yet been given public review 
+     or voting; it is for Standing Committee review and
+     testing. The formal public identifiers have been changed 
+     in the modules and the catalogs.
+         
+ 54. PROCESSING METADATA - A new container element was added as
+     a child of <article>, <sub-article>, and <response> to 
+     describe processing information to help determine the 
+     exact tagset flavor used by this document instance. 
+     (<processing-meta>)
+     Current contents of <processing-meta>:
+      - <restricted-by> - Names tighter schemas, subsets, or
+           Guidelines followed by this document.
+      - <extended-by> - Names extension or superset schemas
+           followed by this document, such as TaxPub.
+      - <custom-meta-group>
+     Several new attributes were added to describe more 
+     completely the flavor/version of JATS in which the 
+     document was composed:
+       - @tagset-family	 (JATS | BITS | STS)
+       - @base-tagset    (Archiving | Publishing | Authoring)
+       - @table-model	 (XHTML |OASIS-CALS | both | none)
+       - @mathml-version (MathML 2.0 | MathML 3.0)
+       - @dtd-version was also revised to be an optional
+           value list (still on <article>)
+       - math-representation - States the ways mathematical
+            expressions appear in this document. Values are 
+            an open, space-separated list, with values 
+            probably one or more of the following words:
+                mathml   tex   latex   images   plain-text 
+            For example, both TeX and images (tex  images)
+            For example, both MathML and TeX (mathml tex)
+            Attribute order is irrelevant. For no math at 
+            all, just skip this optional attribute.
+  
+ 53. EXPANSION OF FIXED ATTRIBUTES LIST: There are four  
+     content-defined attributes which are CDATA values 
+     (undetermined) in Archiving, but which are named value 
+     lists in Publishing/Authoring:
+       - @fn-type 
+       - @person-group-type
+       - @pub-id-type (set up in this module)
+       - @ref-type 
+     In order to give users of Publishing and Authoing
+     more flexibility to name new values without 
+     destroying the benefit of named value lists:
+       - A new value “custom” has been added to the named
+           value list of each of these four attributes.
+       - A new attribute @custom-type has been added to
+           each element that takes one of these attributes.
+     The new attribute @custom-type was also added to
+     Green, so that documents valid to Blue or Pumpkin 
+     would also be also valid to Green.
+     In this module:
+      - The element <article-id> was given the new 
+        attribute @custom-type and "custom" was added to
+        %pub-id-types (defined in the common module).
+     The Best Practice rule (unenforceable in DTDs, but  
+     enforceable in Schematron) is, that if you use the 
+     value “custom” from one of these lists, you should 
+     also record what type of 'custom' in the 
+     @custom-type attribute.                        
+    
+ 52. ISSUE SUBTITLE - Added <issue-subtitle> to 
+     <issue-title-group> optional and repeatable
+
+ 51. ADDED ISSUE TITLE GROUP container element, for associating
+     issue titles, subtitles, and translated titles, when there
+     is more than one <issue>.
+
+ 50. ADDED <issue-title-group> added to <article-meta>
+     (optional, repeatable)
+
+ 49. ASSIGNING AUTHORITY - Added @assigning-authority to the
+     following elements, so that the type-of-identifier and
+     the party-responsible-for-identifier could both be
+     recorded.     
+        - <self-uri>
+        - <pub-date>
+ 
+ 48. JATS "v1.3d2 20201130" becomes 'v1.3 20210610' (second

+     or voting. The formal public identifiers were changed in the 
+     modules and the catalogs.
+  
+ 43. PUB-ID-TYPE - @pub-id-type changed back to a fixed list from 
+     CDATA, reversing the decision of Version 1.2d1. Although 
+     the value list is unchanged, best practice will be documented
+     as using @pub-id-type for type and @assigning-authority
+     for the responsible agency.
+       - for <article-id>
+
+ 42. ASSIGNING AUTHORITY - Added @assigning-authority to the
+     following elements, so that the type-of-identifier and
+     the party-responsible-for-identifier could both be
+     recorded. Previously, these values were both assigned to
+     the attribute @pub-id-type.
+         - <article-id>
+
+ 41. NON-MONETARY SUPPORT - Inside <article-meta> added new
+     <support-group> to hold both funding and
+     non-monetary support descriptions. <support-group> is 
+     both a peer to <funding-group> (backward compatibility)
+     and contains <funding-group>.
+ 
+ 40. PUBLICATION DATE-NOT-AVAILABLE - Inside <article-meta>, 
+     <front-stub>, <event>, and <event-desc>
+     added new element <pub-date-not-available>, as an 
+     alternative to <pub-date>. The meaning is that a 
+     publication date was (for whatever reason) not available. 
+     Presence of the element says nothing about publication 
+     status.
+   
+ 39. VOCABULARY/TAXONOMY ATTRIBUTES - Added 2 new attributes for
+     naming (and possibly linking to) general or controlled
+     taxonomy, vocabulary, index, database or other source of
+     terms (@vocab, and @vocab-identifier) to these
+     elements (which could already take the attributes

+
+     NISO JATS is a continuing maintenance NISO Standard, which
+     requires voting by the ANSI and NISO memberships to be changed. 
+      
+     This draft DTD represents an interim version of the
+     non-normative JATS DTD Suite, as an indication to JATS users
+     the decisions that have been made by the JATS Standing
+     Committee. This draft has not yet been given public review 
+     or voting. The formal public identifiers were changed in the 
+     modules and the catalogs.
+
+ 36. EVENTS - 
+      - Added <event>, which will reside only inside
+        <pub-history>. 
+      - Added <pub-history> to hold <event>s. Unlike in BITS, 
+        <pub-history> will contain ONLY <event>s.
+      - Took <event> attributes from BITS. 
+      - Added <article-version> to model of <event>.
+  
+ 35. PUB-ID-TYPE - @pub-id-type changed from a fixed list to
+     CDATA for all usages of the attribute.
+
+ 34. ARTICLE META MODEL
+     - NO DATE - <pub-date> (optional repeatable) is now
+       followed by the optional new element 
+       <pub-date-not-available>. 
+
+     - ARTICLE VERSION - Added new element <article-version>
+       inside <article-meta> to hold one version number for  
+       the article. <article-version> element may repeat inside
+       new element <article-version-alternatives> to hold 
+       version numbers for this article from different systems.
+ 
+     - PUBLICATION HISTORY - Added new element based on BITS,
+       <pub-history>, to hold <event>s as <history> holds
+       <date>s. New internal elements: <event>, <event-desc>
+   
+ 33. VOCABULARY/TAXONOMY ATTRIBUTES - Added 4 new attributes for
+     naming (and possibly linking to) a general or controlled
+     taxonomy, vocabulary, index, database or other source of
+     terms: @vocab, @vocab-identifier, @vocab-term, and
+     @vocab-term-identifier
+
+      - Attributes @vocab and @vocab-identifier were 
+        added to the elements:
+        - <kwd-group>
+        - <subj-group>
+        - <unstructured-kwd-group>
+
+      - Attributes @vocab-term and @vocab-term-identifier were
+        added to the elements:
+        - <kwd>
+        - <compound-kwd>
+        - <nested-kwd>
+        - <subject>
+        - <compound-subject>
+ 
+ 32. JATS became version "1.2d1" and "v1.2d1 20170631"

+
+75. Custom Metadata Group - Added the attribute @content-type, 
+    @specific-use, and @xml:lang. Inside <processing-meta>,
+    <custom-meta-group> will be allowed to repeat.
+    Not allowed to repeat anywhere else for 1.3d2. Maybe later
+       
+74. OBJECT ID Added <object-id> to: 
+        <alternatives>, <citation-alternatives> 
+
+73. OBJECT ID <object-id> element added to <sec-meta>, which
+      therefore added <object-id> to:
+      - In Green: abstract, ack, app, bio, boxed-text, notes, 
+                  question, sec, and trans-abstract  
+      - In Blue:  app, bio, boxed-text, notes, question, sec
+                  (added the others directly)
+      In some elements (for example, <abstract> in Green)
+      the model will be:
+         abstract  (object-id*, (sec-meta?, label?, title?, 
+                    (%para-level;)*, ...)  >
+      This results in <object-id> being allowed in two places:
+      both at the beginning of <abstract> and inside <sec-meta>
+      within <abstract>. This is a known problem caused by
+      backward compatibility requirements, and it will be
+      what it will be.
+ 
+ 72. EXPANSION OF FIXED ATTRIBUTES LIST: There are four  
+     content-defined attributes which are CDATA values 
+     (undetermined) in Archiving, but which are named value 
+     lists in Publishing/Authoring:
+       - @fn-type 
+       - @person-group-type
+       - @pub-id-type
+       - @ref-type 
+     In order to give users of Publishing and Authoing
+     more flexibility to name new values without 
+     destroying the benefit of named value lists:
+       - A new value “custom” has been added to the named
+           value list of each of these four attributes.
+       - A new attribute @custom-type has been added to
+           each element that takes one of these attributes.
+     In this module:
+      - The element <fn> was given the new attribute 
+        @custom-type and "custom" was added to
+        %fn-types (the footnote type named value list).
+      - The element <person-group> was given the new 
+        attribute @custom-type and "custom" was added to
+        %person-group-types (the person group type named 
+        value list). As an example: 
+           <person-group @person-group-type=”custom” 
+            custom-type=”statisticians”>
+     The Best Practice rule (unenforceable in DTDs, but  
+     enforceable in Schematron) is, that if you use the 
+     value “custom” from one of these lists, you should 
+     also record what type of 'custom' in the 
+     @custom-type attribute.                        
+
+ 71. CUSTOM META - Added all 4 vocabulary attributes to
+     <custom-meta>.
+
+ 70. STRING DATE - Added to models through
+     %references.class; Added to:
+        <related-article>
+     
+ 69. ISSUE SUBTITLE - Added <issue-subtitle> to 
+     <issue-title-group> optional and repeatable
+     
+ 68. ISSUE TITLE GROUP - Added <issue-title-group> to 
+     <volume-issue-group> optional and repeatable
+
+ 67. ASSIGNING AUTHORITY - @assigning-authority attribute
+     added to: 
+       <custom-meta>, <isbn>, <issn>, <issn-l>, <role>, <uri>

+     that provides for alternative block objects such as

+     
+ 64. ADDED SUBJECTS TO WHEREVER KEYWORDS ALLOWED - Added
+     <subj-group> to the following elements through <sec-meta>

+      - ack, app, bio, boxed-text, notes, question, sec
+

+  
+ 59. PUB-ID-TYPE - @pub-id-type (for all tag sets EXCEPT 
+     Archiving) changed back to a fixed list from CDATA for some
+     elements, reversing the decision of Version 1.2d1. Although 
+     the value list is unchanged, best practice will be documented
+     as using @pub-id-type for type and @assigning-authority
+     for the responsible agency.
+        The following were changed back. Therefore, Archiving must 
+     override the following attribute lists to make @pub-id-type 
+     CDATA:
+         - <article-id> (now value list)
+         - <pub-id>     (now value list)
+     But no change to the following, which were CDATA in version 1.1
+         - <issue-id>
+         - <object-id>
+         - <volume-id>
+
+ 58. ASSIGNING AUTHORITY - Added @assigning-authority to the
+     following elements, so that the type-of-identifier 
+     could be recorded with @pub-id-type and the party-
+     responsible-for-the-identifier could be recorded
+     using @assigning-authority. Previously, these value 
+     types were conflated in @pub-id-type. However, for
+     backward compatibility, @pub-id-type was left as
+     the SAME restricted list, with both types intermingled.

+    
+     ANSI NISO JATS is a continuing maintenance NISO Standard, 
+     which requires voting by both the NISO and ANSI memberships 
+     to be changed. This version of the NISO JATS was approved 
+     by ANSI vote on June 10, 2021, so it supersedes all Committee 
+     Drafts as well as the draft version JATS 1.3 2021 (the version
+     submitted for vote), becoming NISO JATS v1.3 20210610 
+     (ANSI/NISO Z39.96-2019).
+
+     The file names and formal public identifiers have been 
+     changed in the modules and the catalogs.
+
+ 19. JATS 'v1.3d2 20201130' becomes 'v1.3 20210610' 
+     (final ANSI vote date)
+     'ANSI/NISO Z39.96-2019' becomes 'ANSI/NISO Z39.96-2021'

+     which requires voting by the NISO and ANSI memberships 
+     to be changed. 
+      
+     This draft DTD represents an interim version of the
+     non-normative JATS DTD Suite, as an indication to JATS users
+     of the decisions that have been made by the JATS Standing
+     Committee. This draft has not yet been given public review 
+     or voting; it is for Standing Committee review and
+     testing. The formal public identifiers have been changed 
+     in the modules and the catalogs.
+
+ 18. TABLE CELLS - Added new elements to <td> using %inside.cell;

+   
+ 16. QUESTIONS AND ANSWERS
+
+     - NEW PE for ANSWERS  - Added new mix "answer para level"
+       to name the elements that may be used at the same
+       structural level as a paragraph, when used inside an 
+       <answer>. This rather awkward parameter entity was created
+       to overcome the DTD determinism issues when using 
+       <explanation> inside an <answer>. In order for 
+       <explanation> to be used at the end of an answer, 
+       it must not be allowed at the paragraph level
+       inside <answer>.
+     
+     - INSIDE TABLE CELLS - Added the question answer class
+       to the contents of table cell using inside cell mix.
+  
+ 15. LINKING TABLES TO SUPPLEMENTARY MATERIAL
+ 
+     - Added the <xref> element (for an internal cross-reference)
+       to the large OR-group inside the body of a <table-wrap>, to
+       be used to make a link to a <supplementary-material>
+       element as a way of recording that a dataset or similar is
+       the data from which the table was derived.
+

+     ANSI NISO JATS is a continuing maintenance NISO Standard,

+     to be changed. This version of the NISO JATS was approved 
+     by ANSI vote on June 10, 2021, so it supersedes all Committee 
+     Drafts as well as the draft version JATS 1.3 2021 (the version
+     submitted for vote), becoming NISO JATS v1.3 20210610 
+     (ANSI/NISO Z39.96-2019).
+
+     The file names and formal public identifiers have been 
+     changed in the modules and the catalogs.
+
+ 34. JATS 'v1.3d2 20201130' becomes 'v1.3 20210610' 
+     (final ANSI vote date)

+     ANSI NISO JATS is a continuing maintenance NISO Standard,

+     of the decisions that have been made by the JATS Standing
+     Committee. This draft has not yet been given public review 
+     or voting; it is for Standing Committee review and
+     testing. The formal public identifiers have been changed 
+     in the modules and the catalogs.
+ 
+ 33. OBJECT ID Added <object-id> to: 
+        <block-alternatives>, <fig-group>, <table-wrap-group> 
+
+ 32. JATS "v1.3d2 20201130" becomes 'v1.3 20210610' (second

+     modules and the catalogs.
+
+ 31. MEDIA MODEL - Added <xref> to media model and graphic model.
+      
+ 30. NEW BLOCK ALTERNATIVES - Added new block element
+     <block-alternatives> to hold block-level processing
+     alternatives, such as the same figure in two languages.
+     The new element can be used anywhere figure is used.
+      
+ 29. ADDED SUBJECTS TO WHEREVER KEYWORDS ALLOWED - Added
+     <subj-group> directly to the following elements:
+      - chem-struct-wrap 
+      - fig and fig-group
+      - graphic
+      - media
+      - supplementary-material (thru fig-model)
+      - table-wrap and table-wrap-group
+ 
+ 28. MULTI-LANGUAGE FIGURE AND TABLE LABELS AND CAPTIONS
+
+     - Made <label> repeatable inside <fig> and
+       <fig-group> to allow both labels and captions to 
+       repeat to be tagged in multiple languages:
+         label   xml-lang="a"
+         label   xml-lang="b"
+         caption xml-lang="a"
+         caption xml-lang="a"
+ 
+     - Made <label> repeatable inside <fig-model> to allow for
+       both labels and captions to be tagged in multiple
+       languages:
+         label   xml-lang="a"
+         label   xml-lang="b"
+         caption xml-lang="a"
+         caption xml-lang="a"
+          
+      - Similar change inside <table-wrap> for the same reason.
+        
+      - Similar change inside <table-wrap-group> for the same reason.
+ 
+ 27. LINKING TABLES TO SUPPLEMENTARY MATERIAL
+ 
+     - Added the <xref> element (for an internal cross-reference)
+       to the large OR-group inside the body of a 
+       <table-wrap-group>, to be used to make a link to a 
+       <supplementary-material> element as a way of recording 
+       that a dataset or similar is the data from which the 
+       tables in the <table-wrap-group> were derived.

+     requires voting by the ANSI and NISO memberships to be changed. 
+     BITS is under continuous maintenance, and is modified at the
+     discretion of the working group.
+      
+     This draft DTD represents an interim version of the
+     non-normative JATS DTD Suite, as an indication to JATS users
+     the decisions that have been made by the JATS Standing
+     Committee. This draft has not yet been given public review 
+     or voting. The formal public identifiers were changed in the

+  
+ 19. NON-MONETARY SUPPORT - Previous support descriptions in JATS
+     used the <funding-group> element, which could only be used to
+     describe monetary support for the research described in the
+     article.
+       Added new element <contributed-resource-group> to hold 
+     descriptions of non-monetary support (such as data, facilities, 
+     or any in-kind support) for the research described in the
+     article.
+     
+     This changed the JATS models in several ways:
+      - Inside <article-meta>, added a new element <support-group>
+        to hold both <funding-group> and <contributed-resource-group>.
+        For backwards compatibility, <support-group> is a 
+        peer to <funding-group> inside <article-meta>, and (as the 
+        path going forward) <support-group> also contains 
+        <funding-group> as a child.
+      - New elements inside <contributed-resource-group> (as its 
+        children or descendants) include:
+          - support-description
+          - resource-group
+          - resource-name
+          - resource-wrap
+          - resource-id
+      - Inside <award-group>, added a new element <support-source>
+        to describe the source of a non-monetary award. The
+        element <support-source> is as an alternative to 
+        <funding-source> (which describes the source of a monetary
+        award).  
+         
+ 18. AWARD ID ATTRIBUTES - Made the award-id attributes match 
+     Green and BITS, adding @award-type and the might link
+     attributes.
+ 
+ 17. BITS "2.0" and "v2.0 20151225" remain unchanged
+   
+     JATS "1.2d1" and "v1.2d1 20171231" became
+     JATS "1.2d2" and "v1.2d2 20180401". 
+
+     No module names were changed.

+ 11. INSTITUTION WRAP ADDED
+     Added the elements <institution-wrap> to the following elements
+     through the institution-wrap.class:
+      - funding-source
+
+ 10. GLOBAL ATTRIBUTES - Added the new parameter entity 
+         %jats-common-atts;
+     to every element in this module. This PE adds (for now) the
+     @id attribute and the @xml:base attribute to every element,
+     whether metadata or narrative.
+     Since the @id in this parameter entity is optional, a second
+     parameter entity jats-common-atts-id-required was also added.
+     The two are kept in sync with the jats-base-atts parameter 
+     entity.

+     Version 0.4                       (DAL/BTU) v0.4 (2011-01-31)
+   
+     This Tag Set is in the process of becoming a NISO standard.
+     The version numbers are starting over from 0.4", as a Trial
+     Use Draft, to be made into "Version 1.0" when the Tag Suite 
+     becomes a NISO standard. Thus, the version number that would
+     have been "NLM Version 3.1 Draft" has become NISO JATS
+     "Version 0.4".
+
+     Details on NISO Trial Use Draft Version 0.4 are available at
+           http://jats.nlm.nih.gov/JATS-0.4.
+

+   
+  5. Updated the public identifier to "v0.4 20110131", 
+     modified the formal public identifier to include "JATS (Z39.96)",
+     and the filename as delivered to include "JATS" and the
+     new version number "0".
+           http://jats.nlm.nih.gov/0.4.
+
+  4. FUNDING GROUP- Allowed <open-access> to repeat within
+     <funding-group>

-     JATS Version 1.1                (DAL/BTU) v1.1  (2015-12-15)
-
-     JATS is a continuing maintenance NISO Standard, which
-     requires voting by the ANSI and NISO memberships to be changed. 
-     JATS 1.1 was approved in late 2015, so the formal public 
-     identifiers were changed in the modules and the catalogs.
-     No model or attribute changes were made at this time. 
- 
- 14. JATS became version "1.1" and "v1.1 20151215"
-
-      =============================================================
-     JATS Version 1.1d3             (DAL/BTU) v1.1d3  (2015-03-01)
-   
-     The changes in this release are in response to NISO 
-     License and Indicators Recommended Practice.
-
-     NISO JATS is a continuing maintenance NISO Standard, which 
-     requires voting by the NISO membership to be changed. This
-     Committee Draft 1.1d3 will be sent to the NISO voting
-     membership, to become (if approved) NISO JATS 1.1.
-     
-     This draft DTD represents an interim version of the
-     non-normative JATS DTD Suite, as an indication to JATS users
-     the decisions that have been made by the JATS Standing
-     Committee.
-
- 13. JATS became version "1.1d3" and "v1.1 20150301//EN"
-
-     =============================================================
-     JATS Version 1.1d2              (DAL/BTU) v1.1d2 (2014-09-30)
-   
-     NISO JATS is a continuing maintenance NISO Standard, which 
-     requires voting by the NISO membership to be changed. This
-     Committee Draft 1.1d2 will be sent to the NISO voting

-     This catalog represents an interim version of the
-     non-normative JATS DTD Suite, as an indication to JATS users

-     NISO JATS Version 1.1d1           (DAL/BTU) v1.1 (2013-11-15)
-   
-     ANSI/NISO Z39.96-2012 (pre-release for V1.0 BITS; Version 1.1d1) 
-
-     NISO JATS Standing Committee met and answered the requests and
-     suggestions from the NISO request forms.
-
-     Details concerning ANSI/NISO Z39.96-2012 JATS-based DTDs,  
-     XSDs, RNGs and supporting documentation are available at
-           http://jats.nlm.nih.gov/1.0/
-
- 11. INSTITUTION WRAP ADDED
-     Added the elements <institution-wrap> to the following elements
-     through the institution-wrap.class:
-      - funding-source
-
- 10. GLOBAL ATTRIBUTES - Added the new parameter entity 
-         %jats-common-atts;
-     to every element in this module. This PE adds (for now) the
-     @id attribute and the @xml:base attribute to every element,
-     whether metadata or narrative.
-     Since the @id in this parameter entity is optional, a second
-     parameter entity jats-common-atts-id-required was also added.
-     The two are kept in sync with the jats-base-atts parameter 
-     entity.

-
-  9. PRINCIPAL-AWARD-RECIPIENT MODEL - Added "contrib-id.class" to 
-     the <principal-award-recipient> through 
-     principal-award-recipient-elements, to hold identifiers for 
-     people, such as publishers-specific IDs, ORCIDs, etc..
-
-  8. PRINCIPAL INVESTIGATOR MODEL - Added "contrib-id.class" to 
-     the <principal-investigator> through 
-     principal-investigator-elements, to hold identifiers for 
-     people, such as publishers-specific IDs, ORCIDs, etc..
-   
-  7. Updated the public identifier to "v1.0 20120330//EN", 
-     modified the formal public identifier to include "JATS (Z39.96)",
-     and the filename as delivered to include "JATS" and the
-     new version number "1".
-

-     Version 0.4                       (DAL/BTU) v0.4 (2011-01-31)
-   
-     This Tag Set is in the process of becoming a NISO standard.
-     The version numbers are starting over from 0.4", as a Trial
-     Use Draft, to be made into "Version 1.0" when the Tag Suite 
-     becomes a NISO standard. Thus, the version number that would
-     have been "NLM Version 3.1 Draft" has become NISO JATS
-     "Version 0.4".
-
-     Details on NISO Trial Use Draft Version 0.4 are available at
-           http://jats.nlm.nih.gov/JATS-0.4.

-     modified the formal public identifier to include "JATS (Z39.96)",
-     and the filename as delivered to include "JATS" and the
-     new version number "0".
-           http://jats.nlm.nih.gov/0.4.
-
-  4. FUNDING GROUP- Allowed <open-access> to repeat within
-     <funding-group>
-
-  3. @SPECIFIC-USE and @XML:LANG - Added the @specific-use and
-     @xml:lang to the following elements:

+     submitted for vote), becoming NISO JATS v1.3 20210610 
+     (ANSI/NISO Z39.96-2019).
+
+     The file names and formal public identifiers have been 
+     changed in the modules and the catalogs.
+
+ 51. JATS 'v1.3d2 20201130' becomes 'v1.3 20210610'

+                                   (DAL/BTU) v1.3d2 (2020-11-30)
+    
+     ANSI NISO JATS is a continuing maintenance NISO Standard, 
+     which requires voting by the NISO and ANSI memberships 
+     to be changed. 
+      
+     This draft DTD represents an interim version of the
+     non-normative JATS DTD Suite, as an indication to JATS users
+     of the decisions that have been made by the JATS Standing
+     Committee. This draft has not yet been given public review 
+     or voting; it is for Standing Committee review and
+     testing. The formal public identifiers have been changed 
+     in the modules and the catalogs.
+      
+ 50. NEW DATE-ONLY CLASS
+       - Added <history> model override, because default
+         JATS uses both <date> and <string-date> in 
+         <history>, while Publishing uses only <date>.
+       - Added <event> model override, because default
+         JATS uses both <date> and <string-date> in 
+         <event>, while Publishing uses only <date>.
+ 
+ 49. OBJECT ID Added <object-id> to: 
+        <abstract>, <ack>, <list>, trans-abstract>
+        <fig-group> (model removed as was same as default) 
+  
+ 48. EXPANSION OF FIXED ATTRIBUTES LIST: There are four  
+     content-defined attributes which are CDATA values 
+     (undetermined) in Archiving, but which are named value 
+     lists in Publishing/Authoring:
+       - @fn-type            (override is in this module)
+       - @person-group-type  (override is in this module)
+       - @pub-id-type
+       - @ref-type 
+     In order to give users of Publishing and Authoing
+     more flexibility to name new values without 
+     destroying the benefit of named value lists:
+       - A new value “custom” has been added to the named
+           value list of each of these four attributes.
+       - A new attribute @custom-type has been added to
+           each element that takes one of these attributes.
+     In this module:
+      - The element <fn> was given the new attribute 
+        @custom-type and "custom" was added to
+        %fn-types (the footnote type named value list).
+      - The element <person-group> was given the new 
+        attribute @custom-type and "custom" was added to
+        %person-group-types (the person group type named 
+        value list). As an example: 
+           <person-group @person-group-type=”custom” 
+            custom-type=”statisticians”>
+     The Best Practice rule (unenforceable in DTDs, but  
+     enforceable in Schematron) is, that if you use the 
+     value “custom” from one of these lists, you should 
+     also record what type of 'custom' in the 
+     @custom-type attribute.
+
+ 46. SEE ALSO - The four vocabulary attributes were added to
+     <see-also>, which is defined in the BITS question-answer
+     model.
+
+ 45. ISSUE TITLE GROUP - Added <issue-title-group> to 
+     <article-meta>  (optional, repeatable)
+ 
+ 44. JATS "v1.3d2 20201130" becomes 'v1.3 20210610' (second 
+     committee draft following the final ANSI/NISO 1.2 vote)

+     or voting. The formal public identifiers were changed in the 
+     modules and the catalogs.
+      
+ 43. ADDED SUBJECTS TO WHEREVER KEYWORDS ALLOWED - Added
+     <subj-group> directly to the following elements:
+      - fig 
+      - fig-group 
+
+ 42. MULTI-LANGUAGE FIGURE AND TABLE LABELS AND CAPTIONS
+ 
+     - Made <label> repeatable inside <fig> and
+       <fig-group> to allow both labels and captions to 
+       repeat to be tagged in multiple languages:
+         label   xml-lang="a"
+         label   xml-lang="b"
+         caption xml-lang="a"
+         caption xml-lang="a"
+ 
+ 41. LINKING FIGURES TO SUPPLEMENTARY MATERIAL
+ 
+     - Added the <xref> element (for an internal cross-reference)
+       to the large OR-group inside the body of a <figure>, to
+       be used to make a link to a <supplementary-material>
+       element as a way of recording that a dataset or similar is
+       the data from which the figure was derived.
+             
+     - Also added the <xref> element (for internal cross-reference)
+       to the OR-group inside of <fig-group> for the same
+       reason, although inside groups will probably be rare.

+        replacing value "conflict", which was left on the list.
+ 
+ 35. NON-MONETARY SUPPORT - Inside <article-meta> added new
+     <support-group> to hold both funding and
+     non-monetary support descriptions. <support-group> is 
+     both a peer to <funding-group> (backward compatibility)
+     and contains <funding-group>.
+ 
+ 34. PUBLICATION DATE-NOT-AVAILABLE - Inside <article-meta>, 
+     <front-stub>, <event>, and <event-desc>
+     added new element <pub-date-not-available>, as an 
+     alternative to <pub-date>. The meaning is that a 
+     publication date was (for whatever reason) not available. 
+     Presence of the element says nothing about publication 
+     status.
+ 
+ 33. BITS "2.0" and "v2.0 20151225" remain unchanged
+      
+   
+     JATS "1.2d1" and "v1.2d1 20171231" became
+     JATS "1.2d2" and "v1.2d2 20180401".

+
+ 31. PERSON GROUP TYPES - Replaced the %person-group-types; parameter
+     entity (allauthors | assignee | author | compiler | curator | 
+     director | editor | guest-editor | illustrator | inventor |
+     research-assistant | translator | transed) with CDATA to allow
+     all types.
+        [Note: Rescinded in JATS 1.2d1. @fn-type is still
+        a value list Note on 2020-51-31]
+
+ 30. ARTICLE META MODEL
+     - ARTICLE VERSION - Added new element <article-version>
+       inside <article-meta> to hold one version number for the 
+       article. <article-version> element may repeat inside
+       <article-version-alternatives> to hold version numbers 
+       from different systems.
+ 
+     - NO DATE - <pub-date> (optional repeatable) is now
+       followed by the optional new element 
+       <pub-date-not-available>. 
+ 
+     - PUBLICATION HISTORY - Added new element based on BITS,
+       <pub-history>, to hold <event>s as <history> holds
+       <date>s. New internal elements: <event>, <event-desc>
+
+ 29. FOOTNOTES
+      - Made @fn-type into a CDATA from a restricted list.
+        Deleted %fn-types; PE, which used to be used.

+        a value list Note on 2020-51-31]
+
+ 28. PERSON-GROUP
+      - Removed string-name.class PE from PE person-group-elements
+        because <string-name> was added to name.class, which
+        person-group-elements already used.
+
+ 27. PERSON-GROUP - Made @person-group-type values into a parameter
+     entity and added values "illustrator" and "research-assistant".
+ 
+ 26. JATS became version "1.2d1" and "v1.2d1 20170631"

+     ANSI NISO JATS is a continuing maintenance NISO Standard, 
+     which requires voting by both the NISO and ANSI memberships 
+     to be changed. This version of the NISO JATS was approved 
+     by ANSI vote on June 10, 2021, so it supersedes all Committee 
+     Drafts as well as the draft version JATS 1.3 2021 (the version
+     submitted for vote), becoming NISO JATS v1.3 20210610 
+     (ANSI/NISO Z39.96-2019).
+
+     The file names and formal public identifiers have been 
+     changed in the modules and the catalogs.
+
+ 44. JATS 'v1.3d2 20201130' becomes 'v1.3 20210610'

+     of the decisions that have been made by the JATS Standing

+     or voting; it is for Standing Committee review and
+     testing. The formal public identifiers have been changed 
+     in the modules and the catalogs.
+     
+ 43. ISSUE TITLE GROUP - Added <issue-title-group> to 
+     <front-stub> optional and repeatable
+         
+ 42. PROCESSING METADATA - A new container element was added as
+     a child of <article>, <sub-article>, and <response> to 
+     describe processing information to help determine the 
+     exact tagset flavor used by this document instance. 
+     (<processing-meta>)
+     Current contents of <processing-meta>:
+      - <restricted-by> - Names tighter schemas, subsets, or
+           Guidelines followed by this document.
+      - <extended-by> - Names extension or superset schemas
+           followed by this document, such as TaxPub.
+      - <custom-meta-group>
+     Several new attributes were added to describe more 
+     completely the flavor/version of JATS in which the 
+     document was composed:
+       - @tagset-family	(JATS | BITS | STS)
+       - @base-tagset   (Archiving | Publishing | Authoring)
+       - @table-model	(XHTML |OASIS-CALS | both | none)
+       - @mathml		(MathML 2.0 | MathML 3.0)
+       - @dtd-version was also revised (see below)
+
+ 41. DTD VERSION - The <article> attribute @dtd-version has been
+     a #FIXED attribute for all of JATS history. This is very
+     convenient when creating documents, but problematic for
+     archives who receive many versions over time. If a document
+     is valid to "v1.3d1"; it is also valid to the latest version
+     and to all older versions. @dtd-version will stay a CDATA
+     attribute, but will be optional, with a list of values, and
+     with no default.
+
+ 40. JATS "v1.3d2 20201130" becomes 'v1.3 20210610' (second

+    
+     ANSI NISO JATS is a continuing maintenance NISO Standard, 
+     which requires voting by both the NISO and ANSI memberships 
+     to be changed. This version of the NISO JATS was approved 
+     by ANSI vote on June 10, 2021, so it supersedes all Committee 
+     Drafts as well as the draft version JATS 1.3 2021 (the version
+     submitted for vote), becoming NISO JATS v1.3 20210610 
+     (ANSI/NISO Z39.96-2019).
+
+     The file names and formal public identifiers have been 
+     changed in the modules and the catalogs.
+
+ 21. JATS 'v1.3d2 20201130' becomes 'v1.3 20210610' 
+     (final ANSI vote date)
+     'ANSI/NISO Z39.96-2019' becomes 'ANSI/NISO Z39.96-2021'

+     JATS Version 1.3d2 (ANSI/NISO Z39.96-2021)
+                                   (DAL/BTU) v1.3d2 (2020-11-30)
+    
+     ANSI NISO JATS is a continuing maintenance NISO Standard, 
+     which requires voting by the NISO and ANSI memberships 
+     to be changed. 
+      
+     This draft DTD represents an interim version of the
+     non-normative JATS DTD Suite, as an indication to JATS users
+     of the decisions that have been made by the JATS Standing
+     Committee. This draft has not yet been given public review 
+     or voting; it is for Standing Committee review and
+     testing. The formal public identifiers have been changed 
+     in the modules and the catalogs.
+ 
+ 20. EXPANSION OF FIXED ATTRIBUTES LIST: There are four   
+     content-defined attributes which are CDATA values 
+     (undetermined) in Archiving, but which are named value 
+     lists in Publishing/Authoring:
+       - @fn-type 
+       - @person-group-type (override is in this module)
+       - @pub-id-type
+       - @ref-type 
+     In order to give users of Publishing and Authoing
+     more flexibility to name new values without 
+     destroying the benefit of named value lists:
+       - A new value “custom” has been added to the named
+           value list of each of these four attributes.
+       - A new attribute @custom-type has been added to
+           each element that takes one of these attributes.
+     The new attribute @custom-type was also added to
+     Green, so that documents valid to Blue or Pumpkin 
+     would also be also valid to Green.
+     In this module:
+      - The element <fn> was given the new attribute 
+        @custom-type. The value "custom" will be
+        documented as a valid footnote type.
+        As an example: 
+           <fn @fn-type=”custom” 
+                         custom-type=”reading-level”>
+     The Best Practice rule (unenforceable in DTDs, but  
+     enforceable in Schematron) is, that if you use the 
+     value “custom” from one of these lists, you should 
+     also record what type of 'custom' in the 
+     @custom-type attribute.                        
+
+
+ 19. JATS "v1.3d2 20201130" becomes 'v1.3 20210610' (second

+     ANSI NISO JATS is a continuing maintenance NISO Standard, 
+     which requires voting by both the NISO and ANSI memberships 
+     to be changed. This version of the NISO JATS was approved

+     Drafts as well as the draft version JATS 1.3 2021 (the version
+     submitted for vote), becoming NISO JATS v1.3 20210610 
+     (ANSI/NISO Z39.96-2019).
+
+     The file names and formal public identifiers have been 
+     changed in the modules and the catalogs.
+
+ 35. JATS 'v1.3d2 20201130' becomes 'v1.3 20210610'

+     ANSI NISO JATS is a continuing maintenance NISO Standard, 
+     which requires voting by the NISO and ANSI memberships 
+     to be changed. 
+      
+     This draft DTD represents an interim version of the
+     non-normative JATS DTD Suite, as an indication to JATS users
+     of the decisions that have been made by the JATS Standing
+     Committee. This draft has not yet been given public review 
+     or voting; it is for Standing Committee review and
+     testing. The formal public identifiers have been changed 
+     in the modules and the catalogs.
+
+ 34. OBJECT ID Added <object-id> to: 
+        <ref-list>
+  
+ 33. EXPANSION OF FIXED ATTRIBUTES LIST: There are four   
+     content-defined attributes which are CDATA values 
+     (undetermined) in Archiving, but which are named value 
+     lists in Publishing/Authoring:
+       - @fn-type 
+       - @person-group-type (override is in this module)
+       - @pub-id-type
+       - @ref-type 
+     In order to give users of Publishing and Authoing
+     more flexibility to name new values without 
+     destroying the benefit of named value lists:
+       - A new value “custom” has been added to the named
+           value list of each of these four attributes.
+       - A new attribute @custom-type has been added to
+           each element that takes one of these attributes.
+     The new attribute @custom-type was also added to
+     Green, so that documents valid to Blue or Pumpkin 
+     would also be also valid to Green.
+     In this module:
+      - The element <person-group> was given the new 
+        attribute @custom-type. The value "custom" will be
+        documented as a valid person-group type.
+        As an example: 
+           <person-group @person-group-type=”custom” 
+                         custom-type=”statisticians”>
+     The Best Practice rule (unenforceable in DTDs, but  
+     enforceable in Schematron) is, that if you use the 
+     value “custom” from one of these lists, you should 
+     also record what type of 'custom' in the 
+     @custom-type attribute.
+     
+ 32. JATS "v1.3d2 20201130" becomes 'v1.3 20210610' (second
