If All, This version of the COSE CMAC draft has updates as identified in the internal changelog. Most notably it suggests code points for new algorithms and includes examples of the two tag varieties using those suggested code points.
If chairs feel like this content is stable enough we can request early allocation of code points as Carsten suggested at the last IETF. If there are any opinions about code point suggestions, those are also welcome. I just chose unallocated positive values from the end of the current IANA registry. I think that there are already collisions of *suggested *values among existing COSE algorithm drafts. Brian S.
