Something I see ignored in the thread is the effect of terminology on 
adoption.  If the terminology is complex or very foreign to the average 
developer, this standard will have issues getting adoption.  I've never 
really been comfortable with "Process Execution".  When I've tried to 
explain it to folks in my dev team, I get the "ha?.... why is it called 
Process Execution".  It's a case of WTMI in the name.

Also, it seems like there is good alignment with OMG's definition of 
Activity in UML.
