Vinny,
Take a look at the following resource. I think it may help with many of the questions that I have seen you asking.
http://www.bpmn.org/Documents/Notations%20and%20Workflow%20Patterns.pdf
This document talk about a number of standard workflow patterns AND how to model thme in both UML and BPMN. So it's easy to compare and contrast the two notations for both strengths and weaknesses.
Thanks a lot for the information, cadams5. I'll take a look at that this evening.
Regards,
vinny
