2.3 Grammar files

This topic lists the changes that have been made to the grammar files.

Catalog files

The following changes were made:

  • Restored certain public identifiers for grammar files to the catalog files. These identifiers, which specify the latest in the 1.x releases of DITA, had been left out of the catalog files for DITA 1.3 and DITA 1.3 Errata 01.
  • Corrected typographic errors in the RNG catalog files for DITAVAL and subjectScheme.

Document-type shells and module files

The following changes were made:

  • In the file rng/base/rng/topicMod.rng, the @dita:DITAArchVersion attribute was defined with a default value of "1.2". This has been corrected to "1.3".
  • In the files dtd/base/dtd/commonElements.mod, rng/base/rng/commonElementsMod.rng, schema-url/base/xsd/commonElementMod.xsd, and schema/base/xsd/commonElementMod.xsd, the @format attribute was added to the <image> element.
  • The files rng/subjectScheme/rng/subjectSchemeMod.rng, rng/technicalContent/rng/referenceMod.rng, and rng/technicalContent/rng/taskMod.rng contain inappropriate declarations of @domains instead of references to the attribute using <ref name="domains-att"/>. These three modules have been updated to use the reference.
