You assume that the interpretation of a term varies from one version of 
a model to another. In practice, that's not unheard of but uncommon. 
Most of the time, the same terms carry the same meanings from one 
version to the next. It's only the new terms added in new versions that 
take on new meanings.

Of course a RDDL document can contain content that's specifically 
relevant to particular versions of a vocabulary. That's what the 
xlink:arcrole attribute is used for.
