Supported Elements & Fields

This page lists every BPMN element, connection, and data construct Stateway recognizes, which fields it reads, and whether each is supported. It is generated and always reflects the engine's actual behavior.

Format is whether a field can be set in BPMN XML, JSON, or both (BPMN·JSON / BPMN / JSON). Status meanings: Supported — fully implemented; Planned, not yet supported — recognized but not yet executed; Recognized, not executed — parsed but intentionally not executed.
