When you read Bernd's use cases after last call, do you think you have 
to add further use cases, which are yet not mapped?

Yes, you were very early with your proposal. Bernd's use cases should be 
able to be mapped till next week.

This is a new use case, that you should add to Bernd's list.
I assume you are showing the RDF XML export by using the RDFa approach.
I might challenge you, by going a step further. If I am a user and would 
import existing RDF XML to reuse existing RDF statements, would itn't be 
nice to export a similar structure?

If I reuse the example
http://www.w3.org/TR/rdf-syntax-grammar/#section-Syntax-multiple-property-elements

<rdf:Description rdf:about="http://www.w3.org/TR/rdf-syntax-grammar";>
  <ex:editor>
    <rdf:Description>
      <ex:homePage>
        <rdf:Description rdf:about="http://purl.org/net/dajobe/";>
        </rdf:Description>
      </ex:homePage>
      <ex:fullName>Dave Beckett</ex:fullName>
    </rdf:Description>
  </ex:editor>
  <dc:title>RDF/XML Syntax Specification (Revised)</dc:title>
</rdf:Description>

If we edited the literal 'Dave Becket' your XSLT have to be improved.

BTW the export of RDF XML using a package only approach would be the 
concatenation of all RDF XML files of the package into a single file.

Svante
