A value of 'AtMostOnce' means that messages received by the RM Destination will be delivered to the Application Destination at most once, without duplication. It is possible that some messages in a sequence may not be delivered. A value of 'AtLeastOnce' means that every message received by the RM Destination will be delivered to the Application Destination. Some messages may be delivered more than once. A value of 'ExactlyOnce' means that every message received by the RM Destination will be delivered to the Application Destination without duplication. /wsrm:DeliveryAssertion/@ordered This attribute, of type xs:boolean, specifies whether, or not, the destination endpoint ensures that the messages within an RM Sequence will be delivered in order by the RM Destination to the Application Destination. Order is determined by the value of the wsrm:MessageNumber. Ordered delivery would mean that the messages would be delivered in ascending order of the value MessageNumber. A value of 'true' indicates that messages will be delivered in order. A value of 'false' makes no claims as to the order of delivery of the messages within a RM Sequence. If omitted, the default implied value is 'false'.
