Diane/John, as promised (a little late due to holiday's in the sun) here is the uri for the W3C Web Services Choreography working groups Requirements Document. I would like to point out that this is very much a heart beat publication. It is a *working draft* and so is in a continual state of change. Furthermore it is a living document that serves to guide the work of the working group so that we remain relevant to the business needs of the community that we serve. Despite the caveats we are very much looking forward to comments from the Technical Committee in particular as it relates to the ways in which we can be complementary to the workings of both groups. Best regards and thank you for your continued support.
