FinalNode must not have outgoing ActivityEdges — model validation fails on activity final node
I am modeling an activity in UML 2.5.1 and my validator flags the model as invalid when an activity final node has an outgoing control flow. My understanding is that the Activities clause defines a well-formedness rule: a FinalNode (both activity final node and flow final node) must not have outgoing ActivityEdges, and violating it makes the model non-confor
