The document is well written and clearly expressed. I have a couple of nits: 1. The paragraphing could be made clearer in my opinion. "Section 2.3 Rationale" is the Rationale for sections 2.1 and 2.2 so I would put this in the section header, "Section 2.3 Rationale for EAP-AKA and EAP-SIM updates". it may be worth putting Section 2.4 as a separate numbering like 3. "Session-Id for PEAP" to keep it separate from 2.1, 2.2 and 2.3. 2. Is "Rationale" needed for the section 2.4 "Session-Id for PEAP"? I suppose that as it is missing altogether the "rationale" is implied but it may be worth adding a sentence to keep consistency in the document.
