I'm not sure that's the only issue.

There may also be problems from an API and processing perspective with 
the non-standard mechanism of associating properties with content 
nodes?

E.g. this ...

<metadata xml:id="m_001>
   <property="snomed:birthdate"/>
</metadata>

... *might* be possible to be made valid RDF, but I don't think it's so 
straight-forward. So then we have the same metadata files with standard 
RDF/XML and non-standard ODF RDF/XML, with little clear benefit for 
anyone.*

I'll defer to Elias to explain if and why my hunch here is right (or 
not).

* I'm actually more comfortable with using the style redirection that 
Florian likes to indicate properties than the xml:id approach for this 
very reason (keep the package RDF files standard and clean). But that 
would still involve a meta:property and/or meta:class attribute on the 
style definition, in which case it's effectively XML window dressing.
