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">
<foo:age>10</foo:age>
</rdf:Description>
The object of the age property denotes a string literal[*].
Proposal B:
<rdf:Description rdf:about="Jenny">
<foo:age>10</foo:age>
</rdf:Description>
<rdf:Description rdf:about="&foo;age>
<rdfs:format rdf:resource="&xsdr;integer"/>
</rdf:Description>
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>
</rdf:Description>
The object of the age property denotes a member of the value space of
xsd:integer.
Proposal D:
<rdf:datatype rdf:property="&foo:age" rdf:datatype="&xsdr;decimal"/>
<rdf:Description rdf:about="Jenny">
<foo:age>10</foo:age>
</rdf:Description>
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">
<foo:age>10</foo:age>
</rdf:Description>
<rdf:Description rdf:about="&foo;age>
<rdfs:range rdf:resource="&xsdr;decimal"/>
</rdf:Description>
The object of an age property denotes an integer from the value space of
xsd:decimal.
[*] A string literal is an old style RDF literal which consists of a
unicode string and language identifier.
