My (maybe wrong) understanding is that the type is not of interest for 
any metadata implementations, but provides only hints to the office 
application which plug-in may be applicable to certain metadata. If this 
understanding is correct, then it should not matter whether we use 
QNames or IRI, because they never will be included in any RDF models. 
QNames are used already in other places in ODF and may save some spaces. 
This may be a reason to use them, just to be consistent with what we do 
in ODF so far. But I'm personally also fine with using IRIs if someone 
names the advantages this has.
