      <section>
        <p>DITA Open Toolkit Release 2.3.3 includes the following bug fixes.</p>
        <ul>
          <li id="2440">Lax processing now tolerates hyperlink references with leading or trailing whitespace in the
              <xmlatt>href</xmlatt> attribute value, such as:
            <codeblock>&lt;xref href=" http://www.example.com" format="html"&gt;</codeblock> Earlier versions of DITA-OT
            would convert the space to its URL-encoded equivalent <codeph>%20</codeph> and fail with an error. The URI
            validation routines have been modified to issue a warning and continue processing in lax mode, but still
            fail in strict mode.

          </li>
          <li id="2017">In certain cases, earlier versions of DITA-OT resolved relative paths to related links from the
            temporary directory rather than from the input DITA map file. Processing has been modified to ensure that
            links are generated correctly regardless of the target file location.

          </li>
          <li id="2458">Several errors in the DITA 1.3 <filepath>subjectScheme</filepath> catalog file were corrected to
            ensure that the module files and entities for the DITA Map Subject Classification Domain are properly
            resolved. Corresponding errata have been submitted to OASIS to ensure the fixes are applied to the official
            catalogs.

            groups.

          </li>
          <li id="2470">The <codeph>mappull</codeph> preprocessing step that pulls content from referenced topics into
            maps has been updated to use the XML catalog to resolve external entity references to their locally cached
            equivalents.

          </li>
          <li id="2474">In PDF output generated by earlier versions of DITA-OT, roman numerals were used to number pages
            in the Notices section, assuming notices are most commonly located in the front matter, which uses roman
            numbering by default. The toolkit now checks whether the <xmlelement>notices</xmlelement> element is inside
              <xmlelement>backmatter</xmlelement>, and uses arabic numbering as appropriate.
            <xref href="https://github.com/dita-ot/dita-ot/issues/2474" scope="external" format="html">#2474</xref>
          </li>
          <li id="2477">When processing topics with unsupported languages, DITA-OT erroneously claimed it couldn't find
            the language <codeph>en_us</codeph> rather than mentioning the unsupported language. The
              <msgnum>DOTX001W</msgnum> message now includes the original, most complete value of the ancestor language
            to assist in troubleshooting.

          </li>
          <li id="2482">In DITA-OT 2.3.2, reference targets for link-like elements such as
              <xmlelement>abbreviated-form</xmlelement> in short descriptions were incorrectly calculated in some cases.
            Processing has been updated to ensure that links are correctly resolved by adjusting references as necessary
            to match the path to the target document.

          </li>
          <li id="2486">The copy-to processing routine failed to update image paths, resulting in invalid references in
            topics copied to locations other than the original or peer directories. Processing has been updated to
            ensure that image references are adjusted as necessary to reflect the location of the referencing document.

        <ul>
          <li id="1599">In earlier versions of DITA-OT, relative paths to cross-references from short descriptions were

              No additional support is added (for example, generated strings for new languages will appear using the

        <p>DITA Open Toolkit Release 2.3 includes the following new features:</p>
        <ul>
          <li id="1116">The <codeph>args.eclipsehelp.toc</codeph> parameter for Eclipse Help, which has not worked
            properly for several releases after it was made obsolete in DITA-OT 1.3, has been removed.

          <li id="1777">DITA 1.3: Initial support has been added for the <xmlatt>orient</xmlatt> attribute on
              <xmlelement>table</xmlelement> elements. These changes allow Antenna House Formatter to render tables in
            landscape mode when the <xmlatt>orient</xmlatt> attribute is set to <option>land</option>. A future release
            will provide extended support for multi-page landscape tables with additional rendering engines.

          <li id="2130">To permit automated building and testing on any platform, the HTMLHelp version of the
            documentation is no longer included in the distribution package. An HTMLHelp version of the documentation
            can still be built on Windows using the downloaded distribution package.

          <li id="2144">SAX pipes can now be configured in Ant <xmlelement>pipeline</xmlelement> tasks. This allows new
            tasks to take advantage of in-memory processing without the need to write out files to disk.

          <li id="2155">The process for generating topic headers in the <option>PDF</option> transformation type has
            been simplified to use a single template with <codeph>mode="insertTopicHeaderMarker"</codeph>. This reduces
            the amount of work needed to format titles differently in the header and body.

            preprocessing module and into a separate step. This improves processing for
              <xmlelement>topicref</xmlelement> elements that use <xmlatt>copy-to</xmlatt> and <xmlatt>keyref</xmlatt>.

        <title>Enhancements</title>
        <p>DITA Open Toolkit Release 2.3 includes the following enhancements and changes to existing features:</p>
        <ul>
          <li id="1860">PDF: Information from the <filepath>README.txt</filepath> files in the
              <filepath>org.dita.pdf2</filepath> plugin have been moved to the “PDF plug-in structure” topic in the DITA
            Open Toolkit <cite>Developer Reference</cite>. Now that all useful information is available in the
            documentation, the <filepath>README.txt</filepath> files have been removed.

          </li>
          <li id="1924">PDF: In earlier versions of DITA-OT, filtering out all rows from a
              <xmlelement>simpletable</xmlelement> element resulted in invalid XSL-FO. When all rows are filtered out,
            the XSL-FO file now contains an empty (but valid) table so that processing can continue.

          </li>
          <li id="2122">Guava libraries are now used to simplify access to collections in Java code (among other
            things).

          </li>
          <li id="2133">HTML: The documentation for the <option>args.hdr</option> and <option>args.ftr</option> options
            now clarifies that header and footer files must be specified using an absolute path. The options have always
            required an absolute path, but the documentation for earlier releases did not include this requirement.

          </li>
          <li id="2140">The <cmdname>dita</cmdname> command will now run using Java headless mode by default. This
            optimizes the use of system resources during a build and prevents the build process from stealing focus from
            other applications.

          </li>
          <li id="2160">HTML: Static text for XHTML tables and figures (such as "Table 5") is now surrounded with a
              <xmlelement>span</xmlelement> element, making it easier to style or hide the static text using CSS. In
            addition, HTML5 output is updated to use semantic elements for figure and table captions.

          <li id="2177">Two members of the <codeph>AbstractPipelineModuleImpl</codeph> class have been marked as

          </li>
          <li id="2179">PDF: The I18N Java and XSLT processing code has been merged into single task. This is not
            visible to most users of the PDF code, apart from a reduction in processing time. It also eliminates the
            need for a <filepath>stage3.fo</filepath> file in the temporary directory; instead,
              <filepath>topic.fo</filepath> is generated directly from <filepath>stage2.fo</filepath>.

          </li>
          <li id="2181">In a previous release, the HTML5 extension point <codeph>dita.conductor.html5.param</codeph> was
            declared but not implemented. The improper declaration was removed and the extension was properly
            implemented.

          <li id="2191">HTML: In previous releases, short descriptions in <xmlelement>abstract</xmlelement> elements
            were rendered as division elements (<xmlelement>div</xmlelement>), rather than paragraphs
              (<xmlelement>p</xmlelement>). Processing has been revised to ensure that short descriptions are
            consistently rendered as paragraphs, regardless of whether they appear in <xmlelement>abstract</xmlelement>
            elements.

          <li id="2207">The order of the <codeph>chunk</codeph> and <codeph>move-meta-entries</codeph> pre-processing
            stages has been switched so that <codeph>chunk</codeph> comes first. This ensures that metadata is properly
            pulled or pushed into the chunked version of DITA topics.

          <li id="2217">HTML: The process for handling <xmlatt>othertype</xmlatt> on a <xmlelement>note</xmlelement>
            element in HTML has been updated to use XSLT 2.0 best practices.
            <xref href="https://github.com/dita-ot/dita-ot/issues/2217" scope="external" format="html">#2217</xref>
          </li>
          <li id="2229">PDF: Earlier versions used an <xmlelement>fo:inline</xmlelement> element as a link target within
            topic titles, which can result in extra white space for certain common customizations. The process now
            places an ID on <xmlelement>fo:wrapper</xmlelement>, which removes the extra element and extra white space.

          </li>
          <li id="2231">XSLT processing now uses a single parameter for message IDs rather than combining one parameter
            for the error number with another parameter for severity. This simplifies message processing and allows a
            greater range of message IDs in the future. In addition, the <msgnum>DOTX071W</msgnum> message will display
            a warning for customizations that use the older, deprecated parameters.

          <li id="2233">Common XSLT utility templates have been rewritten as functions. In addition, XSpec tests have
            been created so that the functions are now covered by automated DITA-OT testing.

          </li>
          <li id="2249">PDF: A reference to the PDF2 catalog has been added to <filepath>catalog-dita.xml</filepath>. In
            previous releases, running <filepath>topic2fo_shell.xsl</filepath> directly would fail because the XSLT
            processor couldn't resolve paths that use the <codeph>cfg:</codeph> scheme.

          </li>
          <li id="2276">HTML5: A new stable ID generation process has been implemented, instead of relying on the
              <codeph>generate-id()</codeph> function. By removing reliance on a dynamic value, this change enables
            automated testing of <xmlatt>id</xmlatt> and <xmlatt>headers</xmlatt> (generated for table accessibility).
            This also speeds up regression testing when comparing HTML output with previous versions.

          <li id="2277">A new ditaFileset function has been implemented to replace list files. This has no visible
            impact for builds, but improves the processing model overall and allows the older way of working with
            individual list files to be deprecated in a future release.

            HTML5 cover processing. These extension points were declared (but not implemented) in DITA-OT 2.2; this was
            addressed in 2.2.5 by removing the declarations. In DITA-OT 2.3, the declarations are restored and properly

          <li id="2243">Publishing failed when using <xmlelement>term</xmlelement> with keyref and chunking, as the
            chunking module created file references with backslashes. Processing has been updated to convert any
            backslashes to slashes before using the <codeph>resolve-uri</codeph> function in XSLT. This ensures that the
            attribute values are valid URI references according to
