Long-lived interactions requirement proposal

Hi all,

As agreed during the conf call on Thursday, here is a proposal on how to add
support for services involved in long-lived interactions to our MOWS
requirement doc.

Regards,

William


Proposal:
---------

In the glossary: Remove all references to conversations and define a session
as "a set of related messages (sent or received by the service) and their
context".

In the requirements list (section 2), add:

- The manageability representation MUST allow monitoring (including state
and access to messages) and control of the current sessions of a service.
- The manageability representation MUST allow metrics to be defined at the
session level.
