Actually what I was trying to get at for this discussion was that its
possible for one topic to have subject identifiers that reference =
subject indictators.  i.e. the topic is a representation (erroneously) =
more than one subject. The point is that while its not desirable to have
conflicting subj inds for a topic - it can happen. My argument therefor =
that it is valid for a resource to be accessed by different URIs an in =
cases this will - like conflicting subj inds - be erroneous.

I disagree. A (single) topic always represents a single subject *by
definition*. (Of course, that might be a complex subject, like "The =
of WG3", but it's still a single subject.)

A single subject, on the other hand, may be represented by multiple =
Within a single topic map we try to avoid this, in order to achieve =
collocation (aka SLUO), but we cannot guarantee that we always succeed.
