<p id="p">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.</p>

<section>
|
|
<title>Major features of DITA 1.3</title>
|
|
<p>The following DITA 1.3 features are supported in DITA Open Toolkit.</p>
|
|
<ul>
|
|
<li>
|
|
<xref keyref="dita13-spec-keyscopes">Scoped keys</xref> supported using DITA 1.3 <xmlatt>keyscope</xmlatt>
|
|
attribute</li>
|
|
<li>
|
|
<xref keyref="dita13-spec-branch-filter">Branch filtering</xref> using <xmlelement>ditavalref</xmlelement>
|
|
elements in a map</li>
|
|
<li>Support formatting based on new XML Mention elements, such as adding angle brackets around elements tagged
|
|
with <xmlelement>xmlelement</xmlelement> and adding <codeph>@</codeph> before attributes tagged with
|
|
<xmlelement>xmlatt</xmlelement></li>
|
|
<li>New highlighting elements <xmlelement>line-through</xmlelement> and <xmlelement>overline</xmlelement></li>
|
|
<li>Support for profiling based on <xmlatt>deliveryTarget</xmlatt> attribute</li>
|
|
<li>Support for the new <xmlatt>orient</xmlatt> attribute for rotating tables</li>
|
|
<li>Profile (filter or flag) based on
|
|
<xref keyref="dita13-spec-profile-groups">groups within profiling attributes</xref></li>
|
|
<li><xmlatt>keyref</xmlatt> and related key referencing attributes supported on
|
|
<xmlelement>object</xmlelement></li>
|
|
<li>New in-topic link syntax using <codeph>.</codeph> in place of the topic ID: <codeph>#./figure</codeph></li>
|
|
<li>Support for additional new elements, such as the <xmlelement>div</xmlelement> element for grouping</li>
|
|
<li>Support <xmlatt>cascade</xmlatt> attribute in maps (processing defaults to the value <codeph>merge</codeph>,
|
|
which is the
|
|
<xref keyref="dita13-spec-metadata-cascade-example">default cascade operation</xref> described by the DITA
|
|
specification)</li>
|
|
</ul>
