Writing rdf:Description/rdf:value in an info panel

I am not able to use rdf:value in an info panel.  The raw data is there, but the Advanced Panel and my info panel do not display the data.

In the XMP Specifications, part 1, an example is given for using rdf:value:

<dc:subject>

    <rdf:Bag>

    <rdf:li>

        <rdf:Description>

            <rdf:value>metadata</rdf:value>

            <xe:qualifier>artificial example</xe:qualifier>

        </rdf:Description>

    </rdf:li>

</dc:subject>

It looks like the use of <rdf:Description> is neccessary.  How can I create the <rdf:Description> wrapper in an info panel script?

Why I'm asking: I'm interested in building a DC Terms info panel.  I would like to use the properties rdf:value and rdfs:label, which is how DCMI uses them.  Perhaps I should use something besides rdf:value such as dc:identifer.

<dcterms:creator>

    <rdf:Seq>

        <rdf:li rdf:parseType="Resource">

            <rdfs:label>Pablo Picasso</dcterms:label>

            <rdf:value>http://id.loc.gov/authorities/names/n78086005</dcterms:value>

        </rdf:li>

    </rdf:Seq>

</dcterms:creator>

Thank you ,
