Hi all,

I spent some time recasting the use cases in terms of payment phases [1], resulting in:

 Web Payments Use Cases - Organized by Phases

The document (still rough) includes:

 * Phases (consumer/merchant flow)
 * Short glossary (Evert’s glossary will make the connections between generalist vocabulary and specialist terminology).
 * Assumptions. (These are broad assumptions factored out from the use cases; the list is mostly to illustrate the idea).
 * Use cases. (Now these are very short statements, organized by phases)
 * Narratives. (One narrative for a web payment scenario, to be followed by much shorter statements to show the variety of 
                      [complete] scenarios we have in mind.). The Online purchase narrative is not yet complete.)

Note that with this document design, architecture and technical requirements are meant to live elsewhere.

If this approach appeals to the group, then more work will be required to make sure that the use case statements (now mercifully short) are accurate and that we have all the scenarios we think are important. 

Comments welcome,
