The Notifier shall format the Notification and transmit it to the Recipient’s message set port in
conformance with the Sender Requirements for the SLE-SM Document Exchange Protocol (3.3.3.1).
The Notifier shall set the confirmation timer to the value of the messageTimestamp of the
Notification message plus the confirmationTimeout for the referenced ServiceAgreement.
The Notifier shall validate a Confirmation received from the Recipient in accordance with the
Receiver Requirements for the SLE-SM Document Exchange Protocol.
The Notifier shall validate exception responses received from the Recipient on the exception response
port in accordance with the Sender Requirements for the SLE-SM Document Exchange Protocol.
If a received Confirmation fails any service management validation requirement specified for its
notified operation type, the Confirmation shall be deemed to be service management-invalid. The
Notifier is not required to further interpret or act upon the service management-invalid Confirmation.
For each syntactically valid UnrecognizedMessageSetResponse received on the exception
response port, the Notifier shall attempt to correlate the content of the UnrecognizedMessage-
SetResponse with a Notification awaiting confirmation. If correlation is successful, the
Notifier shall inform the Recipient, by bilaterally agreed means, of the operation that emitted the
Notification. The Notifier is not required to further interpret or act upon any Unrecognized-
MessageSetResponse that cannot be correlated.
For each syntactically valid InvalidMessageResponse received on the exception response port,
the Invoker shall attempt to correlate the content of the InvalidMessageResponse with a
Notification awaiting confirmation. If correlation is successful, the Notifier shall inform the
Recipient, by bilaterally agreed means, of the operation that emitted the Notification. The
Notifier is not required to further interpret or act upon any InvalidMessageResponse that
cannot be correlated.
The Notifier shall confirm that the invocationMessageSequenceNumber and
ServiceAgreementRef parameters of a Confirmation match the messageSequence-
Number and ServiceAgreementRef, respectively, of a Notification for which the Notifier
is awaiting a Confirmation, in order to associate a Confirmation with a Notification.
NOTE – This is a necessary but not sufficient condition for acceptance of a Confirmation for a
notification. There are additional operation-level matching criteria that must also be met, as
specified under the requirements for the specific operations.
If a validated Confirmation is not received for a Notification by the time the associated
confirmation timer expires, the Notifier shall inform the Recipient, by bilaterally agreed means, of the
operation that emitted the Notification.
