BPMN2 — Contradiction in constraint for Start Events in Event Subprocess

Open Closed All
  • Key: BPMN2-132
  • Legacy Issue Number: 14679
  • Status: closed

  • Summary:

    Apparent contradiction, assuming I'm reading the constraint right.

    The spec states that "An Event Sub-Process MUST have a single Start Event". I interpret this to mean exactly one.
    And yet the spec allows a Start Event with a Multiple or Parallel Multiple event definition. These are short-hand for multiple Start Events, each with a single event definition. Hence a contradiction in functionality and intent.

    Recommend updating the spec constraint to state "An Event Sub-Process MUST have at least one Start Event".
