             Summary: Clarify Source default-outcome and outcomes field descriptions
                 Key: AMQP-131
                 URL: https://issues.oasis-open.org/browse/AMQP-131
             Project: OASIS Advanced Message Queuing Protocol (AMQP) TC
          Issue Type: Improvement
          Components: Messaging
            Reporter: Lorenz Quack


Currently the description of the default-outcome field of the source type is confusing:

1) The specification says: "The value MUST be a valid outcome." This seems to contradict the fact that the field is not mandatory.

2) The specification says: "Indicates the outcome to be used for transfers that have not reached a terminal state at the receiver when the transfer is settled, including when the source is destroyed." My understanding of this was that this *instructs* the receiver to use the specified outcome in the given scenario. This does not make sense. Rob mentioned in a private conversation that the intention is that this *informs* the receiver of the sender's behaviour in the given scenario. In other words, in the given scenario the sender is going to assume that the receiver will use this outcome.

3) My assumption is that the default-outcome should be listed in the "outcomes" field (if specified). This is not mentioned in the specification.
