Hi Ed,
Another question.

I have a xsd which refers to the XML Schema xsd (it has an element which is a schema). I expected/hoped that this would
resolve to a reference to the XSDPackage but it did not because the XSDPackage seems to use a different namespace then
the XML Schema namespace.
I noticed that the XMLNameSpacePackage on the other hand uses the w3.org nsuri.

Is there a specific reason why the XSDPackage has a different non-w3.org namespace uri?

Is there a way that I can let xsd's, which I read through a xsdresource, make use of the XSDPackage instead of creating
their own xsd schema instance?

Yes and the XMLTypePackage also uses a different namespace (because it's
not really the complete model derived from the schema for schemas, but
rather is only the built-in types).

It really is the model derived from that schema.

That was a long time ago. :-P

This allows one bind the schema for schemas directly...

No. I suspect that any model that refers directly to the schema for
schemas will have a hard time serializing and deserializing instances
unless there is a proper binding for the schema for schemas.
