So I don't misunderstand what you are saying. It seems to me like the
comments made by Adrian and you actually requires a "change of meaning",
that is kind of essence of a "cooment", right?

As for what to do with if the TLV is not recognized, it is
intentionally requested from a space where it can be silently dropped
(i.e. "ignored").

    The new TLV Type value should be assigned from the range
    (32768-49161) specified in [RFC4379] section 3 that allows the TLV
    type to be silently dropped if not recognized.

      Type   Meaning                            Reference
      ----   -------                            ---------
      TBD1   Reply Mode Order TLV               this document

What is it that I miss?
