Re: Status of OWL 2 Mapping to RDF Graphs

I'm not sure what part of the documents you are basing this behaviour
on.   As far as I can see our documents leave it completely up to
implementations as to how they are to implement the relationship between
rdf:text literals and plain literals, and this is how it should be.
