With "full nomination" I assume you mean regular nomination (as defined in 5245)?

My point was that WebRTC defines the usage of "nomination", which is the terminology 8445 uses. I am not saying it's forbidden to use aggressive nomination, but as far as I know (I may be wrong) usage of it is not mentioned anywhere.
