  <title>DITA 1.3 support</title>
  <shortdesc><ph id="shortdesc-ph">DITA Open Toolkit <keyword keyref="release"/> 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 extends this foundation to support key scopes and branch filtering along with additional DITA
      1.3 features.</ph></shortdesc>

  <conbody>
    <p id="p">Because DITA 1.3 is fully backwards compatible with previous DITA DTDs and schemas, DITA-OT 2.2 provides
      the 1.3 materials as the default DTDs for processing. The XML Catalog resolution maps any references for
      unversioned DITA doctypes to the 1.3 DTDs. 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.</p>
