XPath support in KeyRef

[Larry . Leung]

Hey,

I've been using Xerces-j 1.4.2 on a project that uses XML Schemas.  Please correct me if I'm mistaken but it looks as if the XPath support in KeyRef
isn't complete.  I'm looking for support for getting the parent (..), parent axis, and predicate processing.  Is this currently in development?  If so what version of Xerces-j is this support going to go into?

Thanks
-Larry
