hi,
for my diploma thesis I'm programming a transformation tool, that transforms XML schemas to UML
class diagrams.
For traversing the xml schema structure I use the xerces xml schema api.

Currently I try to transform keyref-to-key-relations into uml associations. Therefore I need to resolve the Xpath expressions within the IdentityConstraint expressions (XSIDCDefinition) to get
 the attributes/elements the key/keyRef-Element is assigned to.

I tried to use the "org.apache.xerces.impl.xs.identity" package that implements the key-keyref
 concept. So far I didn't reach my goal.

My question:
Is this package (maybe with interaction to other XPath implementations) is able to resolve the xpath expressions (within <xs:selector>- and <xs:field>-elements) to resolve the attribue/element
declaration (XSAttributeDeclaration, XSElementDeclaration) it belongs to?

Thank You

Mathis
