In talking to Frank yesterday, we decided that Tuscany 153 may not be
the problem that is blocking the DAS from implementing T-154. Our
issue is that:
1) We can't create a dynamic root object with the same URI as the
generated DataObjects because the implementation will attempt to
delegate to the generated package when we create the root object,
which will fail.
2) If we use a different URI, the change history does not work
correctly. I assumed this was because of T-153, but Frank believes
that this scenario should be working today and asked for a test case.
Attached is a simple test case that shows the problem. I'll just
attach an XSD instead of the generated types.
