      <title>Software required for core DITA-OT processing</title>
      <p>The DITA-OT requires the following software applications:<dl>
          <dlentry>
            <dt>JRE or JDK, version <keyword keyref="tool.java.version"/> or later</dt>
            <dd>Provides the basic environment for the DITA-OT. You can download the Oracle JRE or JDK from <xref
                keyref="download.oracle-jdk"/>. <note>This is the <i>only</i> prerequisite software that you need to
                install. The remaining required software is included in the distribution packages.</note></dd>

          <dlentry id="antbuild">
            <dt>Ant, version <keyword keyref="tool.ant.version.min"/> or later</dt>
            <dd>Provides the standard setup and sequencing of processing steps. You can download Ant from <xref
                keyref="download.ant"/>.</dd>
          </dlentry>
          <dlentry>
            <dt>XSLT processor</dt>
            <dd>Provides the main transformation services. It must be compliant with XSLT 2.0. The DITA-OT is tested
              with Saxon. You can download Saxon, version <keyword keyref="tool.saxon.version"/> from <xref
                keyref="download.saxon"/>.</dd>

            <dt>ICU for Java</dt>
            <dd><draft-comment author="Kristen James Eberlein" time="11 August 2012">Does the DITA-OT only use ICU for
                Java for index processing? Index processing is what is explicitly mentioned in the installing
                topics.</draft-comment>ICU for Java is a cross-platform, Unicode-based, globalization library. It
              includes support for comparing locale-sensitive strings; formatting dates, times, numbers, currencies, and
              messages; detecting text boundaries; and converting character sets. You can download ICU for Java from

              included in the distribution packages. You can download FOP from <xref keyref="download.fop"/>. You also
