XInclude is already handled by JBossXB (if the parser supports it, which Xerces does). With the JBoss "resource:" url handler it is fairly trivial to include things from the classpath, e.g. | <?xml version="1.0" encoding="UTF-8"?> | | | <xi:include href="resource:org/jboss/some/path/included.xml" | xmlns:xi="http://www.w3.org/2001/XInclude"/> | | If all the new deployers use the helper classes then it would be trivial to enable XInclude for their JAXP parsers as well.
