Thanks, Colin.

Yes, let’s do that. I will draft some lines from an ICNRG perspective 
that Dave could consider including here.

Yes, good point. Dave already noted that “ICN QoS Architecture 
Considerations” (or something in that direction) is more appropriate 
and will change the draft accordingly.

Again, the last call period for this draft is over. If people have other 
comments, please share them now. We will move to IRSG review when the 
new version is ready.
