  <s2 title= "Introduction">
  <p>Extension elements and functions provide a powerful mechanism
  for extending and simplifying what you can do with an XLST processor like
  Xalan. With input and contributions from the XML open-source developer community, we are working on placing the most useful
  extensions in an extensions library distributed with &xslt4c;. If you have ideas and/or contributions you would like to make, please email us at the <human-resource-ref idref="xalandev"/>.</p>
  </s2><anchor name="xalanns"/>
  <s2 title="Xalan namespace">
  <p>We are placing the Xalan extension functions in the XalanExtensions module and we have defined a namespace for this module:</p>
  <p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<code>http://xml.apache.org/xalan</code></p>
  <p>If you are calling &xslt4c;-supplied extensions, we recommend that you define this namespace in your stylesheet element, and call the extension using the namespace prefix that you have associated with that namespace. That way, if we later reorganize how the &xslt4c;-supplied extensions are stored, you won't have to modify your stylesheet.</p>
  <p>For an example that uses this namespace, see <link anchor="ex-nodeset">Example with the nodeset extension function</link>.</p>

  <anchor name="nodeset"/>
  <s2 title= "nodeset">
  <p>Implemented in <jump href="apidocs/class_functionnodeset.html">FunctionNodeSet</jump>, <code>nodeset (result-tree-fragment)</code> casts a result tree fragment into a node-set.</p>
  <note>When you bind a variable to a template, rather than to the value generated by a select expression, the data type of the variable is result tree fragment. For more information, see <jump href="http://www.w3.org/TR/xslt#section-Result-Tree-Fragments">Result Tree Fragments</jump>.</note>
  <anchor name="ex-nodeset"/>
  <s3 title="Example with the nodeset extension function">
  <p>The following stylesheet uses the nodeset extension function to cast a result tree fragment into a node-set that can then be navigated in standard XPath manner. It uses the http://xml.apache.org/xalan namespace to provide access to the nodeset() method in xml.apache.xalan.lib.Extensions.</p>
