Hi,

>>> STIR is not SIP-specific, as all of the discussion about out-of-band has demonstrated. STIR has potential applicability to non-SIP messaging as well as SIP messaging. 
>>> That much said, since STIR implementation has historically been built on top of SIP, that's a focus here - just not an exclusive focus.

> I disagree. I think the gain in readability would be small, and keeping at least the general idea that this can be used for non-SIP mechanisms could potentially serve as a springboard for work (likely elsewhere) for those further specifications.

MSRP can be used with a non-SIP mechanism :) Also, I am fine keeping Section 1 generic.

My main issue is Section 3, and that it is supposed to be "generic" eventhough very much scoped to 2 specific mechanism: MSRP and SIP MESSAGE.

Section 3.1 is about MSRP, and Section 3.2 is about SIP MESSAGE. There is very little "generic" text in those Sections, in my opinion, so why not name the Sections "MSRP" and "SIP MESSAGE", and say that other messaging mechanisms (no matter whether they are SIP-based or not) are outside the scope of the document? I think it would make the document much more clear...

In any case, I will not argue about it, as it is editorial :)

Regards,

Christer
