Subject: [Sip] Comments on history-info

Big question:
Why don't we use multiple History-Info headers, instead of a (potentially VERY long) single header?

I would argue for multiple headers on two grounds.

First, the idea of a proxy modifying history information doesn't sound smart.  If it screws up, it is hard to figure out who screwed up.

Second, the index parameter frees us from worrying about header order, which is a VERY good thing.

Overview:
While the motivation for History-Info is for the initiator of a request to know what happened to a request, it is also of great use to the recipient (End of Section 2 overview paragraph).

Section 1.2:
How is History-Info any different than Via w.r.t. security?

Nits:
Section 2.5, first paragraph, last sentence:
this would like be a local
this would likely be a local
               ^^

Appendix B, message F8, extra space before last angle-bracket in the History-Info line.
