When talking about subsets, please don't get me wrong RDFa is a great 
technique.
ODF 1.2 is just using a subset of RDFa as ODF is a package format and 
able to use RDF/XML within the package to express the statements usually 
expressed by the part of RDFa we are neglecting.

Finally, I got a question regarding a 'trick' to assign an IRI to an 
literal, by using RDFa to create the following statement: <someIRI> 
owl:sameAs "someliteral".
By this, the literal might be used in multiple statements.
This can help having a scenario of an office application in mind, which 
has multiple RDF enabled extension all trying to use the literal in 
their graphs.
Does this work in your eyes?

Thanks in advance,
Svante
