  Subject: multiple partners in CDL


  I'm not sure if this is lurking somewhere in the issues list, which is why I've not raised it directly.

  How should CDL handle a case where there are an indeterminate number of similar partners. For example, the TWIST example shows two potential sellers, but I believe that's just a simplification for explanatory purposes - in reality, the request could be farmed out to any number of sellers, with one being finally selected.  Coping with this would seem to require some sort of collection/set/array construct in CDL - which could be used for relationships, variables, etc.

  <NK>
  I agree that one needs a collection/set/array construct but it seems to me that this is not a CDL issue.

  I am assuming that XML Schema can come to rescue on this but a small example will show us exactly 
  what is needed. Peter, can you craft a CDL example that showcases the need and then we go from there.

  Thanks
  </NK>

  Is this a current issue ?


  (this arose out of working on the actions we got from the coordination/transaction question, but I think is completely orthogonal to that - a completely uncoordinated choreography seeking to find (but not book) the cheapest whatever would have the same requirement)
