I’ve just uploaded [version 04]( Here is a summary of the changes I’ve made and didn’t make. For reference, [here are the diffs](

I’ve taken up Bob’s suggestion to add a sentence about obsoleting RFC6220 in the abstract and introduction.

Benjamin’s comments are addressed below.

> Section 1 references the "IETF Internet Standards Process [RFC2026]", which
> might be spelled better as BCP 9.

> well-known that no informative reference to them is needed?

I am tempted to err on the side of clarity. I do have a similar question about the repeated references to the IASA model. But punted that to the RFC editor.

> Section 2.1 talks about IANA being direted to register values "as directed
> by [...] Proposed, Draft, and full Internet Standards", which is a bit
> stale with respect to "Draft" standards (though not strictly inaccurate in
> the full context).

I replaced Proposed, Draft, and full Internet Standards with “Standard Track Documents[RFC6410]”

I would think that the details of what maintenance means are subject to the specifics of a list and can be captured in SOWs. So no change.

ICANN is the entity the LLC does its business with .. See the latest version of the MoU - to which the reference has been updated. Besides the reference update, no other changes.

I think that is right - with some goodwill this can be seen as an editorial change.

Text now reads:

   *  Intellectual Property Rights and the Registry Operator

      Unless special circumstances apply (see Section 2.1):

      -  All assigned values are to be published and made available free
         of any charges.

      -  The assignment values may be redistributed without

      In any case,

      -  any intellectual property rights of the IETF protocol parameter
         assignment information, including the IETF protocol parameter
         registry and its contents, are to be held by the IETF Trust

> In Section 2.5:
>    In addition, the IETF LLC has the responsibility to ensure long-term
>    access, stability, and uniqueness across all such registries.  This
> Ensuring uniqueness seems rather different from the other two, and on the

My understanding is this: the LLC should make sure that uniqueness is guaranteed. For instance in the case that a registry is transferred from one operator to another, the legacy operator should stop registering new values in the registry and track (if the legacy operator chooses to continue publication) the content of the registries as published by the new operator. That can/should(?) the LLC can/should (?) enforce this.

I have made no changes in the text.

No Changes.

> into 2019 at this point.

Removed mention of year.

Thanks for the comments Benjamin and Bob,
