   * `String` **phaseName** - The optional Schematron phase to be used. Note: this is only available when using the processing engine `pure` or `schematron`. For engine `xslt` this is not available because this was defined when the XSLT was created.
   * `String` **languageCode** - The optional language code to be used. Note: this is only available when using the processing engine `schematron`. For engine `xslt` this is not available because this was defined when the XSLT was created. Default is English (en). Supported language codes are: cs, de, en, fr, nl.
   * `boolean` **expectSuccess** - `true` to expect successful validation, `false` to expect validation errors. If the expectation is incorrect, the build will fail.
+  * `boolean` **failOnError** (since v5.0.0) - `true` to break the build if an error occurred, `false` to continue with the following tasks on error.
   
 Additionally you can use an `XMLCatalog` that acts as an Entity and URI resolver both for the Schematron and the XML files to be validated! See https://ant.apache.org/manual/Types/xmlcatalog.html for details on the XML catalog. Here is an example that shows how to use an inline XML catalog:
