Re: [stir] URN SOS

Just to make sure this part of the thread is addressed:

The context was a discussion about allowing calls that used an SOS URI 
as the call destination (the To: header field value) to be covered by 
STIR. The concern was raised on whether STIR supports that at the 
moment.  There was concern that the discussion of identities in RFC8225, 
constrained the use of 'uri' to really only mean SIP urls. Discussion 
started, and should continue here about whether that's correct, and if 
so, what changes would need to be made.

I don't think anyone intended to propose a _new_ URI. I think 
speaking/typing quickly introduced that confusion, and I believe we're 
past that.

My own opinion is that 8224/8225 don't constrain the use of 'uri' in a 
way that prevents putting the sos urn in the dest, and that the most we 
need to do is think about the consequences of doing so (to look for 
unexpected rough edges), and possibly provide some information guidance 
on their use.
