RegisterSchema errors for include and URN

Question

Hello
I am trying to take advantage of XDB in processing XML documents. The XML Schema is provided by a third party and has several xsd files and a "master" file that imports the rest. I am having two problems with registerSchema.
1) For two of the namespaces, the XML types are defined in one xsd file and the elements in another. The file where the elements are defined INCLUDEs the file with the type definition. This seems like a not unreasonable thing to do. However, if I register the elements file first, I get the error that the included file is not an XDB schema file. If I register the included file first, then try to register the including file, I get the error that the namespace is already registered.
2) Two of the schemas have a URN for the schema URI, not a URL. I get the error Could Not Open urn:foo:bar:bah when I try to register that schema file.
Using includes and urns is certainly within spec. Why aren't these supported?
Thanks

This question is best suited for the {forum:id=34} forum. Make sure you look through the FAQs and pay attention to responses from mdrake or Marco Gralike dealing with registerSchema examples. I do know that you need to register the children (INCLUDE) files first. If you repost your question, include the commands you used to register the files.
