Not entirely. I envisage that the TNC would live on in the form of
normative rules defining how to do (one kind of) name-based merging.

[(2) being the level of individual scopes.] My mind is not yet made up on
this. I guess the main reason I'm holding back on both (1) [level of the topic
map itself] and (2) is that I would really like to decouple the 'namespace'
aspect of scope and the 'contextual validity' aspect of scope. Mixing the
two already tends to cause choas and confusion, and this will get worse when
the time comes (as I believe it will) to make scope more expressive.
