Signature: first_event_multiplicity() : Boolean;
Description: The multiplicity of firstEvent must be 2 if the multiplicity of event is
2. Otherwise the multiplicity of firstEvent is 0.
The OCL used here is not normative.Editor's notes: Added endif.
Expression: if (event->size() = 2)
then (firstEvent->size() = 2) else (firstEvent->size() = 0) endif
Original: if (event->size() = 2) then (firstEvent->size() = 2) else (firstEvent->size() = 0)
