Hi Elwyn,

Thanks for all of your reviews on this so far. I agree with the original 
issue, but I disagree with what I understand to be your preferred 

I agree the definitions are needed to understand this draft. And if 
these were simple definitions, I would agree that this draft should 
simply copy them. But they are not, they are nuanced definitions with 
quite a bit of discussion text. Copying them into this draft would 
require the wholesale copying of 2 sections from RFC 7206, which contain 
about 20 paragraphs and one diagram. That's roughly 20% of the body of 
7206 (not counting front material or references.)

I disagree that this is not an allowable downref. The list in section 2 
of RFC 3967 is a list of examples, not an exhaustive list. We have lots 
of examples of approved RFCs with downrefs to informational RFCs because 
the referenced RFC defined terminology needed to understand the 
dependent document.
