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.
