The intent of the AR PDB spec was not to constrain the means
by which the network operator realizes the edge-to-edge 
behaviour for the PDB. There are various possibilities. 
The assumption section documents one possibility. The one2any
draft documents another possibility.

The authors crafted the paragraph on delay/jitter in response
to the comments on the initial draft. We feel it accurately
captured the sentiment on the list.
