     That UML URI reference is a relative URI.  The W3C has deprecated the
use of relative URIs in namespaces - see [1,2] - but Xalan-J Interpretive
ought to handle them correctly.  However, the interpretive processor
should be processing them correctly.  This is a known problem; see Jira
issue XALANJ-2100.[3]

     XSLTC doesn't have this problem, so the easiest work-around might be
to use that processor instead.  Another work-around would be to rewrite
your name tests from the form "UML:foo" to "*[local-name()='foo' and
namespace-uri='//org.omg/UML/1.3']" which is, admittedly, not very pretty.

Thanks,

Henry
