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.
