Re: Chameleon schemas <include>ing chameleon schemas


chameleon schema
Can you quote a section on this? I have looked at the specification
quite carefully, and can't see it. I have also been careful to
differentiate between "target namespace" (which I have assumed can be
inherited) and "targetNamespace attribute" (which I have assumed
cannot).

Regards

Paul
