Yes, I know; this is exactly the problem.

Let me explain ...

In the preferred implementation, you don't care about the XML. You load 
the RDF/XML into an in-memory model, and access triples as needed. You 
come across a URI in a metadata field, for example, and you simply 
access the triples for it.

If you use XPath, you cannot do that. You are dependent on the 
serialized RDF/XML.

But with a display-property attribute, you can do both; it doesn't 
preclude a simple implementation that just looks at the RDF/XML (absent 
any RDF in-memory model).

Does that make sense?
