+<p>If you wish to generate an XLS file from some XML, it is possible to
+write your own XML processing code, then use the User API to write out
+the document.</p>
+<p>The other option is to use <link href="http://cocoon.apache.org/">Cocoon</link>.
+In Cocoon, there is the <link href="http://cocoon.apache.org/2.1/userdocs/xls-serializer.html">HSSF Serializer</link>,
+which takes in XML (in the gnumeric format), and outputs an XLS file for you.</p>
