The notion that you limit a RDDL to apply to one and only one namespace 
seems like a totally artificial limitation that buys nothing and 
eliminates interesting possibilities.

Aahhh... the RDF tax strikes again.  I want to do something that is 
obvious and straightforward and implicit in the resource/representation 
relationship, and using RDF is going to cost me oceans of arcane totally 
human-opaque syntax.

A machine is entirely capable of detecting the condition that some 
assertions are contained in the representation of a resource and 
inferring the fact that the assertions are related to the resource.  It 
should not be necessary to duplicate the assertion of this 
machine-detectable relationship. -Tim
