6. Discussion of Editors Draft  http://www.w3.org/2002/ws/chor/edcopies/cdl/cdl.html
Skipped.


7. Issues/Proposals against Editors draft

[a] - Schema validation
  How do we do this?
Skipped, since Steve is not here. Propably editorial as Tony observed.

New CDL issue to be logged: what are the levels of validity for a choreography definition?

[b] - Transaction demarcation
  - clarification of the situation today
Nick: same as CDL model overview

  - proposal from Tony
  http://lists.w3.org/Archives/Public/public-ws-chor/2004Feb/0024.html
Tony:
Tony's original proposal based on original Oracle's proposal. Currently implicitly transactions but no attribute to switch on/off transactions. Tony's proposal tries to introduce explicit transaction propagation in CDL. Also, choosing outcome selectively on ending of a transaction. Also, showing transaction propagation mechanisms in the CDL level.

Martin: Currently CDL has WorkUnits, recovery blocks. What is missing?
Tony: I have to look into the current proposal more to see if anything is missing.
Nick: This looks like a good F2F topic.
Martin: Agreed.

NEW ACTION: Chairs to Put Transactions discussion on F2F agenda

Dave: Can we have for the next conf-call discussion on the Levels of Choreography

NEW ACTION: Chairs to Put levels of choreography discussion on next weeks agenda


[c] - roleType
  http://lists.w3.org/Archives/Public/public-ws-chor/2004Feb/0024.html
Tony: maybe a question of language.
Martin: isn't this within the current CDL working draft? See section 2.3.1, 2.3.2.
Nick: It can be done.
Monica: Is role equals to interface?
Nick: no.
Tony: maybe it should be is one-to-one with WSDL.
Nick: everything is there but terminology is confusing.
Martin: Tony, take another look in the current CDL doc and then decide if you want to file an issue on this topic.

[d] - Issues traige
  http://lists.w3.org/Archives/Member/member-ws-chor/2004Apr/0009.html
Martin: ongoing work. We saw Monica's comments and we are going to bring back this work to the WG, so if there any issues the whole group can resolve them.
