Since we are currently editing the WSA spec, we need a placeholder for  
the notions of Choreography and probably orchestration.

I propose the following:

Choreography:

The pattern of interactions, expressed as a pattern of types of  
messages, between a set of service requestors and providers. A  
description of a choreography may include a description of the  
necessary states that give rise to the particular message patterns.

In contract, Orchestration would be:

A mechanism for ensuring that a set of service providers and requestors  
exchange messages in accordance to a choreography.

We would appreciate comments on these definitions, as a new heart-beat  
spec will be published shortly.

Of course, if WS-CHOR comes to consensus on these terms, the WSA will  
be updated acccordingly.
