Hi Christer, All,
I have checked through the -02 version and I found a few small things:

[line 193 - 195, clause 3. 3. The SIP Traceroute Mechanism]
Says "The originating UAC can then generate another INVITE to the same target AoR with a Max-Forwards header field value of 1, which will reach the second SIP, and so on."
Some text is missing here. I guess that a Max-Forwards of 1 will reach the next SIP entity that decrements Max-Forwards, which could be a proxy or B2BUA.

[line 205]
"Enterprise and a Service Provider across a SIP Trunk" should be lower case: "enterprise and a service provider across a SIP trunk"

[line 225]
Contains a reference to [draft-loop-detection]. I don't know if this is a problem but how is the link to a draft in progress kept valid if the draft becomes an RFC?

Regards,
Peter

Excellent! Thank you, Hadriel!

Peter, could you please indicate whether you are ok with the -02 version? Thanks!

Regards,

FYI - this has the changes from the previous comments/discussions, and is hopefully complete/final.
Let me know if I missed something.
