A nit in IKEv2 draft 11: Section 2.16 says this about EAP methods:
"... protocols expected to be used most commonly are fully documented here and in section 3.16."
I disagree about the "fully" part. Section 3.16 has a total of 19 lines of text about EAP methods. In contrast, RFC 2284bis spends about 10 pages to describe the same thing. Recommended fix: remove the word "fully".
