Like Python base class lookup, it searches the workflow definitions in 
the order you specify.

Automatic transitions are only a feature of DCWorkflow, not the workflow 
tool, so DCWorkflow will never see the automatic transition unless you 
kick the other workflow.  In fact, I've been adding transitions called 
"kick", set to "remain in the same state", for just this purpose.  They 
have no effect other than causing automatic transitions, if any are 
pending, to fire.

Ok, it's a hack, but it it allows me to avoid overhauling CMF workflow 
for now. :-)

I agree with Florent.  There should be an event mechanism, and you 
should register an event handler.  (I think there is such a work in 
progress somewhere.)
