I have searched and searched and searched for online documentation on UML 2.0 OR constraints and can find practically nothing. I get on OMG's UML website and can't even begin to find information on diagram elements. What am I doing wrong here???
This is the most recent notation reference that I can find, but it's still for version 1.5..
www.omg.org/docs/formal/03-03-10.pdf
It briefly describes constraints in general, but doesn't really get into how they are applied --such as for Activity diagrams.
I don't believe that the details of modeling an activity diagram have changed significantly in UML 2.0 but then I have not read in full the 2.0 specification.
Here's the official UML 2.0 specification (a bit hard to read): http://www.omg.org/spec/UML/2.1.2/ -> take a look at the Superstructure
For the official UML info, your main resource is http://www.uml.org; there you'll find links to many UML 2.0 resources including articles, tutorials, tools, etc.

Thanks for assisting me, Adrian.
I reviewed the Superstructure document earlier today; it's obviously not something that I can just peruse and expect to comprehend. I just find it hard to accept that there is no simple reference about OR constraints and how they can be applied toward Activity diagrams. I was about to start using forks for what I thought was a perfectly legitimate reason, and then I found one obscure example that used a decision instead of a fork which happens to be, according to you, the correct way to model that scenario. That's pretty frustrating for a beginner!
Again, thanks for the help.
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.
