AS4 5.2.2. relation between missing receipt error and retries

Section 5.2.2.  has the sentence:

"What is the behavior of a Sender that failed to receive a Receipt (even after message retries)?"

This can be read as linking the generation of the error to retries being used.  But retries are configured separately and independently using the PMode[1].ReceptionAwareness.Retry parameters).  Generation of missing receipt errors are configured using PMode[1].ErrorHandling.Report.MissingReceiptNotifyProducer only.
