Hi
i'm not read your paper and presentation yet...
But i've a simple question:
which are the difference between the use of XML scripts to build SIP services
and the use of CPL ... ?
CPL is not considered in 3GPP for the develop of services (if I remember well !!!)
and maybe the use of OSA, considered in 3GPP, for this use it not so userfriendly.
my doubt about your proposal is that it seems to be a replied CPL, isn't it?

Subject: [Sipping] Standardizing the representation of SIP call flows using
XML.
Dear SIP enthusiats:
I am working on a project which involves defining XML scripts to
describe interactions between communicating SIP endpoints (user-agents).
These scripts are used as an input to a customizable user agent to build
build SIP services and may be an interesting way to web host newly
proposed SIP extensions in a standardized way. It may also be a nice way
of quickly bringing new extensions to market without having to go
through the long API standardization process.
Here is a pointer to a talk I presented on the subject:
http://www.antd.nist.gov/proj/iptel/ssp.ppt
and a paper we submitted :
http://www.antd.nist.gov/proj/iptel/src/nist-sip/nist-sip-1.1/docs/white-paper/whitepaper.pdf
The paper is in the written in the context of testing SIP call flows
but I think it can be extended to build services.
Our web tester which you can also access by visiting our project page at
www.antd.nist.gov/proj/iptel incorporates these ideas for a working
demonstration.
I invite your participation in an interest group on the topic if you
have an interest in firming up these ideas and (provided there is
sufficient interest) jointly submitting a proposal to some (as yet
undetermined) standardization body. If you are interested, please send
me mail and if there is sufficient interest I will form a mailing list
for disussing these ideas.
I am posting both the sip-implementors and the sipping mailing list in
the hope that there will be some interest in being able to standardize
the representation of call flows for SIP extensions. Please forgive
possible duplication of this mail in your already crowded mailboxes.
I look forward to hearing from you on the topic.
Regards
Ranga.
