Perhaps a warning message should be emitted if you don't use Saxon.
It is possible to add support for Xalan-Java, which has a systemId extension
function too. The function can be used in a stylesheet like this:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:NodeInfo="org.apache.xalan.lib.NodeInfo">
...
<xsl:value-of select="NodeInfo:systemId()"/>
See http://xml.apache.org/xalan-j/extensionslib.html#nodeinfo.
