Description Martin Chapman 2006-04-11 13:17:34 UTC 
implementation issue from Gary:


. 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.

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)
