12.3.3 BPMNEdge

Connecting Objects [BPMNEdge]

The target [targetElement] and source [sourceElement] of a BPMNEdge may be redefined when the depiction of the source or target of the edge is different than the target [targetRef] and source [sourceRef] of the referenced model element [bpmnElement] (e.g., Message flow finishing on the border of a black box Pool or a collapsed Sub-Process rather than the actual Flow Node within the Pool or Sub-Process). In such case, the targetElement and/or sourceElement of the BPMNEdge must point to the appropriate BPMNShape or BPMNEdge.

The source [sourceElement] and target [targetElement] of a BPMNEdge can never be a BPMNShape with participantBandKind set (i.e., only Choreography Activity can be source or target of the BPMNEdge not the Participant Bands).

Note that for Message Flow with an envelope decorator, the envelope decorator should be at the midpoint of the message flow. BPMN DI does not provide an interchange of the bounds of the envelope decorator.

The “diamond” at the source of the Conditional Sequence Flow should not be depicted when the source of a Conditional Sequence Flow is a Gateway. In other words, when the source of a Conditional Sequence Flow is a Gateway, the Conditional Sequence Flow looks like a Sequence Flow.

Even though DataInputAssociation(s) and DataOutputAssociation(s) (Directed Data Associations) always point to DataInput(s) or DataOutput(s) as sources or targets within the BPMN model, they are mostly depicted as starting or finishing on the border of a different depicted element and thus, the target [targetElement] or source [sourceElement] of the BPMNEdge must be specified.
