Take 2: how does existing RDF software handle this datatypes test?

In the interest of exploring this issue with the expectation
of datatyping rather than its total absence, could those of
you who have provided results based on Dan's original example
please indicate results from the following extended examples,
which includes explicit datatyping:

Case A: (global typing)

<rdf:RDF
xmlns="file:/home/connolly/w3ccvs/WWW/2000/10/swap/test/dt10-premise.n3#"
    xmlns:dc="http://purl.org/dc/elements/1.1/"
    xmlns:ex="http://example/vocab#"
    xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
    xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#">

    <rdf:Description>
        <rdf:type rdf:resource="#Film"/>
        <dc:title>10</dc:title>
    </rdf:Description>

    <rdf:Description rdf:about="#mary">
        <ex:age>10</ex:age>
    </rdf:Description>

    <rdf:Description rdf:about="http://purl.org/dc/elements/1.1/title">
       <rdfs:range rdf:resource="http://www.w3.org/2001/XMLSchema#string"/>
    </rdf:Description>

    <rdf:Description rdf:about="http://example/vocab#age">
       <rdfs:range rdf:resource="http://www.w3.org/2001/XMLSchema#integer"/>
    </rdf:Description>
</rdf:RDF>

Case B: (local typing)

<rdf:RDF
xmlns="file:/home/connolly/w3ccvs/WWW/2000/10/swap/test/dt10-premise.n3#"
    xmlns:dc="http://purl.org/dc/elements/1.1/"
    xmlns:ex="http://example/vocab#"
    xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
    xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#">

    <rdf:Description>
        <rdf:type rdf:resource="#Film"/>
        <dc:title>
           <rdf:Description>
              <rdf:type
rdf:resource="http://www.w3.org/2001/XMLSchema#string"/>
              <rdf:value>10</rdf:value>
           </rdf:Description>
        </dc:title>
    </rdf:Description>

    <rdf:Description rdf:about="#mary">
        <ex:age>
           <rdf:Description>
              <rdf:type
rdf:resource="http://www.w3.org/2001/XMLSchema#integer"/>
              <rdf:value>10</rdf:value>
           </rdf:Description>
        </ex:age>
    </rdf:Description>

</rdf:RDF>

And, per Dan's original example, for each case:

Suppose I asked you:
    does that document say that
    there's something with a dc:title?
I hope you'd say: yes, of course.
Now... suppose I ask:
    whatever that title is, let's call it X.
    Does that document also say that there's
    something with ex:age of that same X?

Do you consider the results to be logically correct?

Thanks,

Patrick
