Re: Question about Accept-Language

Aside from the viewpoint that this specific query possibly belongs on the sip-implementors list.

Can I note that people should continue to monitor this list for any issues regarding SIP documents in transit within the IESG (i.e. post publication requested). 

You can only discard your participation when we get the IESG to finish chewing the last one - at the current rate of progress that is about 3 years time.
