  <s3 title="Version of Xerces to use"> 
<p>The &xslt4j-current; has been tested with &xml4j-used;. &download; For information about including xerces.jar on the system class path, see <link idref="getstarted" anchor="classpath">Setting up the system class path</link>.</p>
<p><em>Important</em> You may experience unpredictable anomalies if your Xalan and Xerces builds are not in synch. If you download an update to Xalan, check the release notes to determine which version of Xerces you should use.</p>
<note>You can use Xalan with other XML parsers, but it is up to you to implement liaisons to those parsers. Your liaison class should extend <resource-ref idref="XMLParserLiaisonDefaultDoc"/> and implement <resource-ref idref="XMLParserLiaisonDoc"/>.</note>

<s3 title="To-do tasks for future &xslt4j; releases">
   <p>The &xslt4j; team is hard at work on &xslt4j; version 2.0, which represents a major redesign of the Xalan XSLT Processor.
    The main goals of this redesign are as follows:</p> 
	 <ol> 
		<li>Provide ease of access and usability of &xslt4j;, and encourage greater participation from the open source community 
    in the ongoing design and development process</li> 
		<li>Reduce code size and complexity</li>
		<li>Improve performance and simplify optimization.</li> 
		<li>Produce more localized, less-intertangled modules</li> 
		<li>Begin the adoption of the TRaX (Transformations for XML) interfaces</li>
     <li>Take advantage of the <jump href="http://www.megginson.com/SAX/Java/index.html">SAX 2</jump> and <jump href="http://www.w3.org/TR/DOM-Level-2/">DOM level 2</jump> packages</li>
    </ol>
    <p>For an overview of the 2.0 design, see <jump href="http://xml.apache.org/xalan/design/design1_1_0.html">Xalan-J 2.0 Design</jump>. The source tree (still pre-alpha) is in the <jump href="http://xml.apache.org/websrc/cvsweb.cgi/xml-xalan/java/src/">Apache CVS Repository: xml-xalan/java/src</jump>. Pre-alpha Xalan-J 2.0 <jump href="http://xml.apache.org/xalan-j/apidocs/index.html">Javadoc</jump> is also periodically updated on the xml.apache.org Website.</p>
    <p>As part of the xml.apache team, members of the &xslt4j; team are also exploring options to upgrade the integration of all
     the xml.apache projects, including Xalan, Xerces, Cocoon, and FOP.</p>
    <p>The more individuals who join in the design, development, testing, documentation, and use of
    &xslt4j; the better for us all in the xml.apache.org open source community! Watch the <human-resource-ref idref="xalandev"/> for more information and for ideas about how you can get involved.</p>
