You could stick it into the XSL stylesheet itself (using XInclude 
perhaps an entity). Then you can cache the Templates object. Then when 
you transform, you could access the included XML with something like:

Source XML:


<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
xmlns:my="my" version="1.0">

   <my:something boo="foo"/>

   <xsl:template match="/">
