You misunderstand me. The point is that RDF "the language" isn't  
necessarily fixed. There might be new versions, just as their might  
be new version of Unicode. The issue is whether your document should  
normatively reference a *particular* version or normatively reference  
the current "and any future one".

Obviously, that's what I'm trying to do.

But sometimes it may make sense to refer to a fixed version in one  
document and not in another. For example, allowing any future version  
of XML be a legal OWL/XML syntax is probably ok. Claiming that your  
semantics is an extension of *any future* RDF semantics probably isn't.
