Current text says only one element, out of two or more, SHOULD be selected . What if choice contains all non-blocking conditional elements and none of them evaluate to true? . What if you have non-observable conditions around choice elements that are interactions? These non-observable conditions could equally evaluate to false. . Semantics of choice need to be clear from a monitoring and execution perspective, therefore would suggest changing SHOULD to MUST. 10577 1 martin.chapman 2006-07-18 19:44:19 +0000 proposal at: http://lists.w3.org/Archives/Public/public-ws-chor/2006Jun/0005.html add the following to the end of the para in above proposal: "If no activities are selected, this MUST result in a runtime exception." add text in primer on how to model choice with no action (one choice element with no action activity) propsal accepted on 18th July 2006 meeting
