Implementors Guide not normative?

It's looking to me like the best way to capture the H.248 implementer's
guide is to issue in February an H.248 V2 that is at least V1+IG. Rather
than argue abstractly about what else might be in V2, I thought I'd list
the post-V1 proposals that have been accepted so far:

APC-1911: Change of Capabilities indicated in H.248 ServiceChange ( )

APC-1913: Improved Auditing in H.248 Version 2 ( )

APC-2002: Signal on Root for H248v2 ( )

AVD-2068: Improved Auditing in H.248 Version 2 [amends APC-1913] ( )

D93: Handling of multiple pending transactions in H.248 (

D129: Extendable Context Properties for H.248 v2 (

So, that's 5 proposals (note that AVD-2068 amends, or replaces, APC-1913).
Please take this information into consideration when you form an opinion
about what should be in V2 and the timing of V2. AVD-2131 for the Dublin
meeting ( ) shows
V1 + IG + the accepted proposals listed above. Marcello Pantaleo (your
friendly H.248 editor) is also creating a document that would show V1 + IG.
