4. ACTION on Gary to follow-up with issuer (Kohei) on issue 1102
Gary thinks that Kohei was ill last week, but this action is IN PROGRESS.

5. ACTION: to the chairs to figure out what are the WSDL's exit criteria.
The chairs have discovered that the Web Service Description Language group exit criteria have not been defined yet.  It was agreed to liaise with that group next week at the W3C Technical Plenary.  Mark as DONE.

6. ACTION: Yves to look into hosting around the June AC meeting.
Yves said yes he can get a room in Sofia Antipolis, and requested that the group let him know the dates that they wanted.  DONE.

Martin suggested that we accept this offer and just decide precise dates later. 
Nick said that he wanted to avoid the 6 - 8th June, 2005 as there was a conference in Eindhoven, The Netherlands that he wished to attend on those dates.  Abbie pointed out that WS-I were meeting in Europe the following week (week of 13th June, 2005) and he would like to be able to combine the trips.  After some discussion the favoured dates seem to be 1, 2, 3 June or 9, 10 June.  It was agreed to ask people to e-mail dates they could do/prefer and make a choice of the dates at the face-to-face next week. 

6. Face 2 Face Planning
-----------------------
It was agreed to make sure that the exit criteria are on the agenda and also to add in the priorities agreed at this meeting.

There will be a dial in facility and this information will be circulated.
ACTION:  Chairs to ensure that dial in information for the F2F is circulated to group members.
ACTION:  Chairs to insure the consideration of the exit criteria for the group is on the agenda for next week's face-to-face meeting. 

7. Issues Triage
----------------
All done

8. Issues requiring discussion
------------------------------
This was all about prioritisation of the issues requiring discussion.

Of the new ones registered in Bugzilla 1128 and 1129 are from the document and require discussion, the other 2 that still require assigning are Kohei's, and Gary is seeking clarification on the substance of those. 

Martin explained that all last call comments must be resolved though this does not mean solving all of them - some may be closed with no change to the specification. 

Charlton (http://lists.w3.org/Archives/Public/public-ws-chor/2005Feb/0022.html), Gary/Steve (http://lists.w3.org/Archives/Public/public-ws-chor/2005Feb/0018.html), Oracle (Martin - http://lists.w3.org/Archives/Public/public-ws-chor/2005Feb/0019.html http://lists.w3.org/Archives/Public/public-ws-chor/2005Feb/0020.html), Sun (Monica - http://lists.w3.org/Archives/Public/public-ws-chor/2005Feb/0021.html) and Abbie (http://lists.w3.org/Archives/Public/public-ws-chor/2005Feb/0023.html) have submitted mails with suggested priorities.

Several of the issues gave rise to some debate as to what their priority marking should be.  In these cases a vote was taken on one vote per company basis.  The table below records the majority verdict but not the details of the polling.

* 1129 Tony said that although Choreology would very much like to see the ability to extend choreographies included, they had regretfully come to the conclusion that it would require too much work both within Choreology and within the group to arrive at a watertight and agreeable proposal in reasonable time for version 1.  We in Choreology now therefore had to view this as a version 2 feature, although of course we would be very supportive if someone else were able to make a proposal.  Reluctantly others agreed with this conclusion and so it was agreed to close this issue with no change to the specification. 
*996 ACTION: Tony to respond to Arthur Ryman and Kevin Liu e-mails on multiple response messages in WSDL 2.0

In general the idea is to talk about the P1 issues first at the face-to-face meeting next week, but the chairs will also try to work in some others that look easy to solve.  Martin and Steve also emphasised that they needed proposals to solve all of these issues.
