It seems I'm the one who misunderstood. I've dug a little deeper and
your are right that the difference between local and external is just
one level of entry/exit actions. So your approach of adding an
intermediate state does work.
From the UML specs it's hard to extract the exact definition of a local
discusses this subject and warns about the pitfalls of using composite
states to de-clutter a state machine.
[I think there is a more general concept here, the same as having an nth
level history, a transition could have a level specification, n=0 is
external, n=1 is local, and n=infinity is the way I misinterpreted local
transitions. I need some real practical examples ...]
