[mdt-bpmn2.dev] BPMN 2.0 spec inconsistency?

[Bob Brodt <bbrodt@xxxxxxxxxx>]

Hello devs,

I've been asked to look into what may be an inconsistency in the BPMN 2.0 specification. It was first discovered by a user, and reported as a bug in the eclipse BPMN2 Modeler here [1]

According to the BPMN 2.0 spec, it appears as though a SubProcess MAY be the source or target of a MessageFlow but looking at the class diagram for MessageFlow, only InteractionNodes may be sources and targets and SubProcess clearly does not implement InteractionNode. Is this a bug? If so, does the problem lie within the spec, the bpmn2 metamodel or both?


Thanks!
Bob
