Right. What I was up to is that scoping a topic-basename association
limits the validity of the 'use' (or assignment) of a particular name
as a BASENAME and that it does not mean that the used name isn't a valid
(simple-)name for the topic if the scope does not apply. (Either something
is a name for something or not, that fact does not change)

In other words, we must be carefull not to mix the special semantics
of the topic-basename associations (or characteristic assignments) with
the general semantics of using names for 'things'.

Regarding the example, we must be careful not to infer from the scoped
*basename* assignment of 'economie' to a topic, that 'economie' isn't
a valid *name* for the topic unless the scope {Dutch} applies.

If the scope {Dutch} doesn't apply 'economie' is not a valid
BASE NAME, no more.

"economie" is an unambigous name 'in dutch' for the topic --economy--.
If the author wasn't sure, "economie" should not be a basename but some
other kind of name (without the semantics of unambiguity).

Sorry, I should have made my distinction between basename and name
much more explicit in my first reply.

So, again: does that make sense to you ? ;-)
