I think I suspected some limitation around libxml2 myself. It was hard to tell without enough experience with it. As for the schema examples, they were crafted to demonstrate the condition. So I could have defined the namespace either way - shared/unique, with consistent results. Having said that, when designing schemas with high reuse and extensibility, the shared namespace will start to make sense, given the right context and utilization. Very useful in larger, shared projects.

The external validator was java based. There are a few other commercial tools out there that would have worked just as well. The original schema from which I modeled the personal.xsd, is part of a larger set managed by a vendor. The set has been in use for several years, by us and other clients. So alteration was never in scope. And besides, clients using C++ and Java processors have no trouble consuming (and generating) XML based on these schemas. I don't think I would have, either. It's just that my particular effort required the use of Perl.

I believe I will take a different approach to validating the XML, at the expense of labor :-(. I will also attempt to get in touch with the xmlsoft, when time permits, to see if they'll view this as something to be solved (or have solved) in a future release. You appear to be very knowledgeable on this subject as well ! I thank you for your willingness and overall attitude.
