So if it's a term for an RDF property, dereferencing it should give you something that says it's an RDF property. When I look up http://www.w3.org/2005/04/xpath-functions/#max I don't get confirmation that that URI refers to an XQuery function; rather, I am told that http://www.w3.org/TR/2005/WD-xpath-functions-20050404/#max refers to an XQuery function. > This use of namespaces and namespace documents has been a subject of > discussion on this list in the past, so I wanted to draw your > attention to it. > > One thing I didn't get to do in time for this round was make it a > proper RDDL document.

(double-checking... http://www.rddl.org/#nature is like rdf:type and each purpose is like an RDF property... ok...) I think a/the nature (i.e. rdf:type) of an XQuery function is owl:FunctionalProperty. I can't think of any relevant uses of rddl:purpose. -- Dan Connolly, W3C http://www.w3.org/People/Connolly/ D3C2 887B 0F92 6005 C541 0875 0F91 96DE 6E52 C29E
