Fair enough. Clearly the S idiom provides a means to define
a pairing of lexical form and data type, but I don't see any
of the S idiom variants proposed thus far as being nearly as
economical as the P, DAML, or U idioms. I.e.

   Bob ex:age "10" .
   ex:age rdfs:range xsd:integer .


   Bob ex:age _:1 .
   _:1 rdf:value "10" .
   _:1 rdf:type xsd:integer .


   Bob ex:age <xsd:integer:10> .

and the P and DAML idioms are currently in use and understood
by (presumably) a non-trivial body of the RDF community, so why
adopt yet another idiom if the present ones do the job? Especially
when those idioms demand a proliferation of (unnecessary) URI sets
where a single data type URI is sufficient?
