  <shortdesc>DITA Open Toolkit <keyword keyref="release"/> provides an initial preview of features for the upcoming
    OASIS DITA 2.0 specification. This preliminary processing support is provided on the basis of the latest DRAFT
    versions of the DITA 2.0 DTD and RelaxNG grammar files from OASIS (as of March 2020).</shortdesc>

  <conbody>
    <p id="grammar-files">DITA documents that reference the draft grammar files can be parsed, and where features
      overlap with DITA 1.3, those features will work as expected.</p>
    <ul>
      <li id="3453">
        <p>
          <ph id="include">The new <xmlelement>include</xmlelement> element can be used to reference text or XML content
            from other files. In addition to the processing mandated by the specification, DITA-OT also supports the
            character set definition and line range extraction options previously provided for
              <xmlelement>coderef</xmlelement> elements (see
            <xref keyref="extended-functionality"/>).</ph>
        </p>
      </li>
      <li id="3462">
        <p>
          <ph id="specializations">The new <xmlatt>specializations</xmlatt> attribute, which replaces the DITA 1.x
              <xmlatt>domains</xmlatt> attribute, can now be used as an alternative method of declaring specialized
            attributes.</ph>
        </p>
      </li>
      <li id="3463">
        <p>
          <ph id="outputclass">The <xmlatt>outputclass</xmlatt> attribute can now be specified as a flagging behavior in
            DITAVAL files. This allows you to flag an element with a CSS class keyword that will be added to the
              <xmlatt>class</xmlatt> attribute value in the generated HTML. Output classes allow you to pick up
            pre-defined styles from existing web frameworks, and are more easily overridden with custom CSS files than
            the inline <xmlatt>style</xmlatt> attributes generated by DITA 1.x flagging options such as
              <xmlatt>color</xmlatt> and <xmlatt>backcolor</xmlatt>.</ph>
        </p>
      </li>
      <li id="3464">
        <p>
          <ph id="simple-table-titles">Titles can now be specified on simple tables, and
              <xmlelement>simpletable</xmlelement> entries now support row and column spanning attributes.</ph>
        </p>
      </li>
      <li id="3483">
        <p>
          <ph id="topic-based-classes">Where DITA 1.x defined conflicting <xmlatt>class</xmlatt> values for
              <xmlelement>linktext</xmlelement>, <xmlelement>shortdesc</xmlelement>, and
              <xmlelement>searchtitle</xmlelement> in maps and topics, the new draft of DITA 2.0 uses the topic-based
              <xmlatt>class</xmlatt> value in all cases. Processing is updated to recognize the updated value when these
            elements are used in maps.</ph>
        </p>
      </li>
    </ul>
    <note id="more-to-come">Other new or revised features proposed for DITA 2.0 are not yet supported. Additional
      features will be implemented in future versions of DITA-OT as the specification evolves.</note>
