  <title>DITA 1.3 support</title>
  <shortdesc>DITA Open Toolkit <keyword keyref="release"/> provides preliminary processing support for the upcoming
    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.</shortdesc>

  <conbody>
    <p>Because DITA 1.3 is fully backwards compatible with previous DITA DTDs and schemas, DITA-OT 2.2 will provide the
      proposed 1.3 materials as the default DTDs for processing. The XML Catalog resolution maps any references for DITA
      1.2 doctypes to the 1.3 DTDs, for example. 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. Documents created with the proposed OASIS DITA 1.3 DTDs are the only ones
      ever likely to have features that invoke the specific new 1.3-based processing support.</p>

    <p>Because this support is based on a yet-to-be-approved version of the proposed OASIS DITA 1.3 specification, if
      you choose to investigate any 1.3-based function, be aware that the 1.3 implementation in this version of the
      toolkit is preliminary. Upon final approval of the DITA 1.3 standard, toolkit developers will review the
      implementation to make certain that it conforms to the final specification.</p>
