Excellent!  I've also been pretty puzzled by UML.  Its diagrams never
tell me the key things I need.  For occam/CSP/JCSP/CTJ, all I've ever
drawn are the data-flow network diagrams - layers of them.  It shows us
all the players in the system and how they relate to each other.  And it
maps 1-1 with the CSP code structures we write - in whatever language.

Is it those diagrams you are adding into UML?  An excellent trick!  Next
time I show such things, I shall claim that they're just UML and all the
OO people will sit up nicely ;-)

Thanks,

Peter.
