I am very pleased to hear it!  If you have any remaining indexes in
the NorZIG context set, perhaps you would propose them here for
inclusion in one of the other existing sets?

Yes, precisely.  (In fact, AFAIK it's the _only_ such "protocol
dependent fashion" -- that clause smells of over-generality to me.)

Yes.

Yes.  Or the client might want to extablish a short name corresponding
to a context-set URI that is not mentioned at all in the Explain
record; or might just not want to bother thinking about what's in the
Explain record.

Others will have to answer that, but may I just say that I'd love to
see a situation where there is no need for a separate NorZIG set.
