Hi

I guess each of the "shall we allow multiple representations" needs to be handled on a case-by-case basis, but generally speaking I understand that the chairs and ADs aren't too enthusiastic with too many ...

What 3GPP really wants for Christmas is the draft to be completed. Somebody must take a decision on this soon.

cheers

Andrew: If you look at the SIP grammar, this obviously will not be the only header with multiple representations.  We simply keep on adding to that list.

Beyond that, I think discussing about this to a great degree will not lead us anywhere.  I am interested in this issue from an academic point of view, but pragmatism says that we proceed further without delays.

As an individual, I am happy to allow the draft to proceed with the alias defined (or not).

Thanks,
