I don't understand the distinction you are making between 'namespace' 
aspect of scope and the 'contextual validity' aspect of scope. Can you 
say more about that distinction or how I would distinguish one from the 

Along the same lines, are there any authoring practices or topic map 
software that would support my making that distinction (after I 
understand its nature)?
