My main concern with this draft is that it carries both a set of
requirments and a possible solution. I suggest to split it in two.

On the requirments:

>     [R-PSPOOF]
>         Prevent spoofing of DNS responses by passive attack

I do not see how you can spoof DNS while being purely passive. Do you
refer to an off-the-path active attacker?

Editorial:

> Deployment of the new security mechanism compliments DNSSEC.

Complements? (I know I do not speak english but I'm nevertheless
confused.)
