Agenda item 1:
Chair (A.B.) briefly announced goals of the session: going through the issues in the Protocol I-D, finding out and closing the issues.

Agenda item 2:
Chair (A.B.) went through the agenda and the agenda bashing. Proposed agenda was accepted.

Agenda item 3:
Issue: DTDs vs. Schemas.
Answer: Current version of the I-D available at:
http://search.ietf.org/internet-drafts/draft-ietf-spirits-in-03.txt
gives examples of utilizing DTDs as well as Schemas. SPIRITS does not mandate using one vs. another. These are just examples

Agenda item 4:

    - Subscribing to multiple DP's;
It is questionable whether SIP SUB/NOt supports such actions and whether SPIRITS needs such a way. Resolution: outside of today's scope

    - Example services:
      - ICW (section 3 of SPIRITS I-D)
      Resolution: no comments, proceed with the I-D.

      - ICIDD service call flow (section 5 of SPIRITS I-D)
      Resolution: no comments, proceed with the I-D.
      
      Other services? VKG proposed SMS to SIP IM as an example service for the I-D.
      Resolution: Flash theis idea on the mailing list to check the idea against SPIRITS charter and to gage WG's interest.

    - SPIRITS specific security considerations;
    - Unfinished portions of Section 4
    Resolution: It is just a matter of time. These sections will be finished shortly.

Agenda item 5. Conclusions:
One of the outstanding issues, besides security, is SPIRITS MIB. Igor Faynberg proposed re-use of PINT MIB. WG will look into this.  Consensus to start work on MIB when Protocol is ready to go to the Last Call. Maybe PINT MIB is  a good starting point. Ask PINT MIB Doctor (Dan Ramascanu) for assistance.


Respectfully submitted,
