[DPF] Are there any RDF properties which cannot be used as DPF properties?

Hi Dan,

This message contains a response to comments on

(http://www.w3.org/TR/2004/WD-DPF-20041122/#s3 suggests that this  
might be the case, since RDF properties can lack datatype  
restrictions, and don't use the DOM approach adopted in DPF, but  
instead allow XML schema-style datatyping via a datatype URI).

Response:

Yes. Any properties that do not conform to the RDF usage patterns for  
delivery context would not be accessible in DPF.
