Unfortunately I can't take the existing IBM JDom out of the classpath as it
is being used by the xPression application and I can't run the risk of
breaking it. I would just use IBM's JDOM but the version supplied does not
support XPath. What I require is a way of overriding the classpath just for
my user exit code...
