Thats what I meant with workplan: We should define the minimum
requirements (maybe in steps - e.g. DNSSEC), but during the
discussion (as we see already) a lot of things will pop up, which
are not relevant for "minimum requirements for interoperablity", but
should be harmonized. So after finishing the ETSI guide, we could
continue an further work.

Done.

Fine, now I get your point. We discovered already, that there
may (or already is) be a feedback on the treatment of numbers
in conjunction with ported numbers and personal numbers,
especially the need to "park" numbers.
In VISIONng two weeks ago we already decided to broaden the
status of UPT-numbers in the admin part of the TRC
Unassigned
Assigned to TSP
Assigned to ENUM SP
Parked
Depending on the final policy, you may have now a bunch
of different tranactions, e.g. we may allow ENUM only numbers,
as you suggested.
If ENUM only is not allowed, we also have solved the problem
Paul mentioned to trigger the deregulation (this has also
decided to be done by the TRC, if necessary).
Just to answer a potential question on ENUM-only beforehand:
calls to ENUM-only UPT numbers will be terminated on the PSTN
in the UPT environment by routing to an announcement.
