2.2.4.3 id Element

The WS-Routing <id> element MUST be present as a child element of the <rp:path> element. The content of this element uniquely identifies the message across all MSMQ QMs.

If the <Msmq> element is not present in the message (see section 2.2.6), the <id> element MUST be ignored.

If the <Msmq> element is present in the message, the <id> element MUST contain a string that begins with "uuid:", followed by an index number of type xs:unsignedLong that identifies the message, followed by "@", and then followed by a GUID string that identifies the sending QM.

The sending QM GUID SHOULD<7> be identical to the <SourceQmGuid> child element of the <Msmq> element.

The <id> element corresponds to the Message.Identifier attribute of the ADM Message data element. For details, see [MS-MQDMPR] section 3.1.1.12.
