This release expands on Xerces' experimental support for XML Schema 1.1 (see Xerces-J-bin.2.11.0-xml-schema-1.1-beta.zip) by providing implementations for the simplified complex type restriction rules (also known as subsumption), xs:override and a few other XML Schema 1.1 features. Xerces-J 2.11.0 also introduces experimental support for XML Schema Component Designators (SCD). It fixes several bugs which were present in Xerces-J 2.10.0 and also includes a few other minor enhancements.

  • Implemented support for the vc:typeAvailable, vc:typeUnavailable, vc:facetAvailable and vc:facetUnavailable attributes for conditional inclusion processing in XML Schema 1.1 documents
  • Implemented support for allowing xs:group as a child of xs:all in XML Schema 1.1 documents
  • Made several enhancements to the support for assertions in the XML Schema 1.1 implementation
  • Improved the ways in which the XML Schema API exposes values and identity constraint information
  • Fixed a bug where XMLSchemaValidator.findSchemaGrammar() was not getting called for substitution groups
