OK

Why? And why does this follow from the previous sentence? Not ALL 
vocabularies can be so identified, but that is not what is being said 
here.  I see nothing wrong with saying that the namespace name 'rdf' 
identifies the rdfV vocabulary, for example.

It does not seem to me that this assertion is a matter of absolute or 
objective fact one way or the other, but that is it not an 
unreasonable claim or one likely to be misunderstood.
