There was a problem hiding this comment.
7301 is informative currently, should it be normative?

Normative references specify documents that must be read to understand or implement the technology in the new RFC, or whose technology must be present for the technology in the new RFC to work.
&
Note 1: Even references that are relevant only for optional features must be classified as normative if they meet the above conditions for normative references.
No feature in the TLS 1.3 spec, optional or required, needs ALPN to work. We merely cite places where it needs to be taken into consideration if it is in use. It could be argued that it is an "optional feature" of TLS (as a whole), but not of this document, thus I don't think it meets the qualifications to be normative. I think staying as informative is correct.

There's a bunch of text that specifically mentions ALPN, some of it with normative statements. If those normative statements can't be understood, optional feature or not, then it's normative. |
