Hi, I read the draft and I think the semantics are ok (although John's point about multiple proxies with these tags is a good one). One use which occurred to me - but which is no doubt controversial - is whether a proxy/B2B which is an SBC could provide a feature tag indicating it is an SBC - so that UAs which register and call through it could skip adding ICE candidates. (My point is merely that I suspect other uses for this capability will be found - even if you think this particular idea is mis-guided).
