## Comments

### S5

* For "exterr", does this mean that a server that supports RFC 8914 in full
  should reply with:

    "exterr=0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24"

  Without some attempt at summarizing this (e.g. "=0-24") there is a penalty
  to supporting more error codes over time. Of course, summarization schemes
  do introduce their own parsing complexity. :-/

  This is obviously a minor concern/comment, though.  (No action needed.)

### S7

* It occurs to me that an encrypted resolver might return correct information
  for itself but this information could still be incorrect for other
  resolvers that are part of a shared serving infrastructure (i.e. those
  servers comprising the service behind a resolver VIP).

  It might be worth noting some operational guidance like all resolvers
  in a group SHOULD have consistent RESINFO?
