<p class="p" id="dita-13-spec-support__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>
