Hi Patrick,
Yes, Xerces-C supports schema identity constraints. There are a few ways
in which beginning users go wrong when using schema identity constraints;
the most common is that they think default namespace applies to XPath
expressions when it doesn't. In order to give you any more useful
feedback, you'd have to post a (small) instance/schema pair that Xerces
says is valid but which you think should be invalid.
Cheers,
Neil

Please respond to
xerces-c-dev
Ok,
Looks like that there is a lot of code about identity constraints in
xerces.
What is the purpose of this code?
Would there by any advantage of using key-keyref in my schema when parsing
with xerces?
Thanks
Patrick
