COMMENT:
----------------------------------------------------------------------

Hi,

It seems to me there are places where 2119/8174 keywords would make sense.
Few examples, with suggestions:
   If the initiator is configured to use a post-quantum preshared key
   with the responder (whether or not the use of the PPK is mandatory),
   then it will include a notification USE_PPK in the IKE_SA_INIT
   request message as follows:
>>MUST include

   If the initiator needs to resend this initial message with a cookie
   (because the responder response included a COOKIE notification), then
   the resend would include the USE_PPK notification if the original
   message did.
>>MUST (or SHOULD?) include
by the way, if it is a resend of the message described in the paragraph above,
then "if the original message did" seems superfluous.

   Otherwise the responder replies with the IKE_SA_INIT message including a
   USE_PPK notification in the response:
>>MUST reply

      initiator and the responder.  The responder can use the PPK_ID to
      look up the corresponding PPK value.  Not all implementations are
      able to configure arbitrary octet strings; to improve the
      potential interoperability, it is recommended that, in the
      PPK_ID_FIXED case, both the PPK and the PPK_ID strings be limited
      to the base64 character set, namely the 64 characters 0-9, A-Z,
      a-z, + and /.
>>RECOMMENDED

   values 3-127 are reserved for IANA;
Maybe it's just because I'm not used to that wording, but why "reserved for
IANA" ?  The table seems to qualify them as unassigned.
