Considering that I have not heard anyone argue against code being the 
reference, I assume there is consensus on that. Anyone disagrees on 
that? If not, I'll add that to the draft.

Again, from the previous IETF meeting (logs at 
http://www.ietf.org/jabber/logs/codec/2010-07-26.txt) I thought most/all 
agreed with having a fixed-point reference, but not "force" 
implementations to be bit-exact with it. The current draft already 
mentions that and leaves it up to the codec draft to specify the exact 
conformance requirements.

Well, that may be the only one that's still being debated. I think that 
can be resolved after adopting the draft.

Cheers,
