Validator Rollup (#7844)
Browse files Browse the repository at this point in the history 
* Revision bump.

* Revision bump for amp-playbuzz changes in #7450

* Revision bump.

* Allow filtering by HtmlFormat (AMP, AMP4ADS) in the code generator.

* Revision bump.

* Revision bump due to Github pull.

* Code generation now driven by a variable LIGHT, which is broader than the previous GENERATE_DETAILED_ERRORS distinction. LIGHT implies filtered for specific format (AMP or AMP4ADS, and only amp.validator.validateSaxEvents, and no detailed errors.

* Generate ValidatorRules.directAttrLists and globalAttrs and ampLayoutAttrs, reducing overhead by indirection.
