You are correct, Paul.  It is not possible to define the structure of MOBY  
Objects in XML schema (for some of the same reasons that it is impossible  
to define RDF-XML documents in XML Schema)

There's a belief "out there" that all XML documents can be represented in  
XML schema, and I've been attacked by audience members during  
presentations and workshops when I say this isn't true... but it isn't  
true!!

The Moby XML is "defined" by the Moby Object ontology, much as RDF-XML can  
be "defined by" an OWL ontology (please don't attack me for saying it that  
way - I KNOW that this is backwards from the way OWL and RDF actually  
work!).  The resulting flexibility in document structure cannot be handled  
by XML Schema.

It sucks for us, since we want to use WSDL... but it's a painful reality.
