T2 Reliable Messaging w/o CPA or VIA...

Title: 

Section 10.2 (line 1695) says:

This 
parameter information can be specified in the CPA or in the MessageHeader 

But I can't find anywhere in the MessageHeader to set the 
following parameters:

mshTimeAccuracy
reliableMessagingMethod
ackRequested
retries
retryInterval
persistDuration

This seems like a formidable problem when 
doing reliable messaging (ackRequested) without an intermediary (no 
Via).  If we put this information back in the MessageHeader, why is it 
also in the Via?  This was in the MessageHeader in v0.91 but it was taken 
out... probably shouldn't have been.
