ORA-19201: Datatype not supported when validating XML against an XSD

Question

Hello.
Info: using Oracle 10.2.0.1.0, Java components are installed.
I've created an XML view using ora:view, which is validated against a registered XSD. This view is created successfully.
But when I SELECT * from this view, it gives ORA-19201 - Datatype not supported.
Can't understand why. I've matched the XML to the XSD, and the datatypes all look fine to me. I've referred to the XSD using the XMLFORMAT.CREATEFORMAT option. When I use the same option to specify "NO_SCHEMA", it returns the correct XML, but we need to validate it against the XSD.
I'm thinking one of two things has happened here:
1. I've made a mistake with either my registration, or how I've used XMLFORMAT to refer to the XSD.
2. There's a bug in Oracle.
My money's on 1. Can anyone help?
Thanks,
Ray.

Hello Geoff, I didn't want to send any code until I knew someone was willing to look at it (there's a lot of it).
Here is the XSD:

The view is created with no errors. Selecting * from it, however, gives:
ORA-19201 - Datatype not supported
Marrying the XML to the XSD shows nothing obviously wrong.
