I think this a good projection of the choices
to be ranked as prefer/can live with/can't live with

Draft Question for Webont:

RDFCore are considering a number of ways of representing datatyped values
in RDF graphs and RDF/XML.  We would like to know WEBONT's preference
amongst the following options.  Please could you rank them in order of
preference, and identify any which would be unacceptable.  Unacceptability
is not a matter of taste; to label an option as unacceptable, a critical
requirement that cannot be met must be identified.

Proposal A:

   <rdf:Description rdf:about="Jenny">

The object of the age property denotes a string literal[*].

Proposal B:

   <rdf:Description rdf:about="Jenny">
   <rdf:Description rdf:about="&foo;age>
     <rdfs:format rdf:resource="&xsdr;integer"/>

The object of an age property denotes a string literal [*] from the lexical

space of xsd:integer.

Proposal C:

   <rdf:Description rdf:about="Jenny">
     <foo:age rdf:datatype="&xsdr;integer>10</foo:age>

The object of the age property denotes a member of the value space of

Proposal D:

   <rdf:datatype rdf:property="&foo:age" rdf:datatype="&xsdr;decimal"/>
   <rdf:Description rdf:about="Jenny">

Proposal D is proposal C with some syntactic sugar (the rdf:datatype
declaration) so that it is not necessary to put an rdf:datatype attribute
on every use of the age property.

Proposal E:

   <rdf:Description rdf:about="Jenny">
   <rdf:Description rdf:about="&foo;age>
     <rdfs:range rdf:resource="&xsdr;decimal"/>

The object of an age property denotes an integer from the value space of

[*] A string literal is an old style RDF literal which consists of a
unicode string and language identifier.
