Hey all,

just an question concerning a StateMachine with no context classifier.
Am i right, that as state machine with no classifier can specify call
events for several classifiers. If so, it should be easily possible, to
use a StateMachine as an input/output labeled transition system,
shouldn't it? Or am i totally on the woodway?
Since now,i used StateMachine exclusivly within an context classifier,
which determines the possible call event of the transition trigger.

Thx
Timothy

Of course, in the end it is a just a model that you need to interprete.
If you want to interprete transition names or the operation names attach
to the edges as labels, that's all fine.

On the one hand I'm glad that UML gives you so much freedom, on the
other hand you really have to spend a lot of effort if your input model
needs to exercise only a well-defined subset of the available features
(otherwise it's garbage in-garbage out).
