<wsrm:DeliveryAssertion mode="[AtLeastOnce|AtMostOnce|ExactlyOnce]" ordered="[xs:boolean]"? ... > /wsrm:DeliveryAssertion A policy assertion that makes a claim as to the delivery assurance policy observed by the destination endpoint. /wsrm:DeliveryAssertion/@mode This required attribute specifies whether or not all of the messages within an RM Sequence will be delivered by the RM Destination to the Application Destination, and whether or not duplicate messages will be delivered. 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 processed in order. A value of 'true' indicates that messages will be processed in order. A value of 'false' makes no claims as to the order of processing of the messages within a RM Sequence. If omitted, the default implied value is 'false'.
