Ted Ross commented on DISPATCH-148:
-----------------------------------

Possible solution:

Add an attribute 'preserveDa' to listener and connector with type ["no", "in", 
"out", both"], optional and defaults to "no".

On connections with "no", strip delivery annotations both inbound and outbound. 
 "in" means strip outbound only, "out" means strip inbound only, "both" means 
don't strip.

> Messages that ingress from endpoints outside of the router should have any 
> x-opt-qd headers removed from the delivery properties.
> Occasionally developers will re-use received messages for transmit and not 
> clear the delivery properties.  This can result in mysterious dropping of 
> messages due to anti-looping (i.e. the x-opt-qd-trace header shows the 
> message passing through the router already and the message is dropped).
