BPMN11 — Inclusive Event-Based Decision

We may need a way to model more general logic patterns for incoming events. For example, in response to an RFQ, a supplier may send either a decline, or a quote and (as a separate message) terms & conditions. The logic pattern for this use case is

Decline XOR ( Quote AND Terms )

If the Decline is accompanied by a memo giving reasons, then the logic becomes

( Decline AND Memo ) XOR ( Quote AND Terms )

We want to open up three event receivers initially (four in the second case). Then, as a Quote arrives for example, we want to close the receives for Decline and Memo — since we don't expect those any longer — but keep the receive for Terms & Conditions open. When those have arrived as well, the inclusive event-based gateway is complete.

Suggested Resolution:
Close, No Change: This issue is out of scope for the RTF and will be addressed by the response to
the BPMN 2.0 RFP.
