?? Sorry, maybe I am not following your sharp and blunt ends. (I 
assume the blunt end is the subject and the sharp end is the object 
in an RDF triple, right?)

If we were to write a class name at the blunt end we would be 
attributing a property to the *class*, right? Do you mean something 
like

xsd:integer rdf:type rdf:DataType .
