Considering how forthcoming the CASE companies have been and how good (8^) 
) are the tools, it will be a fight to get to support any AUML at all. I do 
agraa that were we can simplify UML 2.0 we should try to. I find it a very 
"bulky" for the lack of better word notation.

ps: Michael, I also personally agree that the icons would work better. I'm 
just playing devil's advocate, because I know that we will be questioned in it.
