PMode[1].ErrorHandling.Report.ProcessErrorNotifyConsumer

PMode[1].ErrorHandling.Report.ProcessErrorNotifyConsumer: This Boolean parameter indicates whether (if "true") the Consumer (application/party) of a User Message matching this P-Mode should be notified when an error occurs in the Receiving MSH, during processing of the received User message.

This only works if the receiving MSH has been able to map a receiving message to a PMode. The @pmode attribute on AgreementRef is optional and AgreementRef itself is optional. In their absence, a PMode can be inferred from e.g. Service/Action combinations. It should be possible to state how messages that cannot be mapped to a particular PMode are reported and to whom.
