Richard, Garret has been railing against rdf**s**:datatype, not 
rdf:datatype. Of course, there is no such thing as rdfs:datatype, so 
I've assumed all along he means rdfs:Datatype, analogous to his other 
comments on rdfs:Literal. See http://www.w3.org/TR/rdf-schema/#ch_datatyp .

rdfs:Datatype is, of course, quite distinct from the RDF/XML datatype
