Implementors Guide not normative?

Since the IG is not normative on H.248v1 (or any other "v" for that matter),
and v1 is not interoperable and possible not even implementable without it
(correct me if I'm wrong), it seems like we have two alternatives:

1. Move forward with v2 ASAP and hope that absolutely _nobody_ deploys a v1
entity. (If it were a true v1-compliant entity, it would be broken because
v1 is broken; if it were a v1+IG entity, it wouldn't be v1-compliant.)
2. Produce a v1 Corrigendum so that a v1 entity is viable.

Personally as I've mentioned in previous meetings I would support the
approval of v2 to bring in the changes from the IGs. I feel that a 80
page corrigenda to a 134pg H.248v1 isn't very practical. It will also
help interoperability if you receive a v2 message then you know exactly
to expect. At previous interops different groups have implemented
different IG versions.

With regards to the 2 year guideline it would be 20 months between the
decision and the consent date for the recommendation. By the time the
consent period is finished and the recommendation is published it would
be very close to 2 years. We have had other recommendations in SG16
which have not aligned to the 2 year guideline.
