mm1@
In late March I wrote this summary proposal and have received an 
affirmative nod from Dennis Krukkert to provide us assistance for model 
updates for v3.0.  We have open questions on fork-join and may find we 
have updates for v2.0.  In the interim until those are better understod, 
I would request the team to consider this proposal for one of our next 
meetings - 20 April or the informal F2F on 28 April 2004.

John Yunker, Anders Tell, Lars Abrell, Rajesh Pradhan, from a modeling 
perspective are you amenable to this proposal? Comments welcome.

See below the summary proposal sent 28 March 2004.
=======================================================================================================================
Dennis,
We discussed this work item you submitted in the F2F in February 2004.

Work item 51: UML convention change
Description: Use the choice connector (diamond shape) instead of the 
"or-fork" and the same shape for the "wait-for-all=false" join as in UML.

Discussion points:

   * Related to XOR.
   * Fork and join are paired. Identify what this could mean to BPSS
     and address in v3.0.

It is important to note we spent a great deal of time in the F2F first 
day discussing the underlying conceptual model for BPSS. We understand 
that in a future version we will discuss in greater detail. Such as 
indicated by John Yunker, UML activity diagrams are moving to petri 
nets. Decision is only a fork where conditions on
both sides are exclusive.   In v2.0, we are trying to balance backward 
compatibility and maintaining the base known concepts in BPSS as well as 
look to the future (such as reference above).

Recommendation:
For v2.0, close this work item with no action and address as in v3.0.

Dennis, if you can give us greater details and assist in this process 
(and analysis), we would welcome your contribution and insights. I would 
encourage any other team members to comment and we can finalize in a 
summary proposal for vote. Thanks.
