Thanks for answering quickly.
I'm still not done with this problem. just to make sure, I get it right:
To determine the element or attribut declarations the
key/keyref/unique-elements belong to, I have to evaluate the
selector/field XPath expressions manually while traversing the XSModel?
There's is no way to use the
org.apache.xerces.impl.xs.identity package in conjunction with the
org.apache.xerces.impl.xpath package for this problem?
Thanks again,
Mathis
