<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'.
