DITA 1.3 support
DITA Open Toolkit 4.0 provides processing support for the OASIS DITA 1.3 specification. Initial preview support for this specification was added in version 2.0 of the toolkit; version 2.2 extended this foundation to support key scopes and branch filtering along with additional DITA 1.3 features.
Because DITA 1.3 is fully backwards compatible with previous DITA DTDs and schemas, DITA-OT provides the 1.3 materials as the default grammar files for processing. The XML Catalog resolution maps any references for unversioned DITA document types to the 1.3 versions. All processing ordinarily dependent on the 1.0, 1.1, or 1.2 definitions continues to work as usual, and any documents that make use of the newer DITA 1.3 elements or attributes will be supported with specific new processing.
