David,

A good suggestion, but it might be easier for IANA to just have two
subsections in the IANA Considerations section:

- What IANA Now Needs to Do (this could be nothing, but should be
explicit)

- What IANA Already Did in RFC XXXX

and keep this section identical to the original RFC.

Of course, we should ask Michelle what she would like to see! :-)

<tp>

Why?

The purpose of an RFC is to provide information for the community so my
starting point is what is it that the community wants to see.  Once that
is determined, then then is the time to ask Michele and company what
they want to see to ensure that the section meets those requirements.

I make frequent reference to the IANA Considerations section of RFC
going back decades, because they constrain what can and cannot be done
now, and it is a pain when the information is scattered across multiple
RFC, or when the key RFC is badly worded, ambiguous.  Examples of  the
latter keep cropping up.

So, I would say that an IANA Considerations should be complete and
should never say this is what we did last time and here is a delta for
you to (mis-)apply.

A minor example of this is RFC7950 which many cite in the IANA
Considerations of an I-D containing a YANG module in order that the YANG
modules is registered with IANA.  Wrong!  All that RFC7950 says is that
the procedure is described in RFC6020 so you have to get out RFC6020 to
know what to do and the sort-of-obsolete RFC6020 then has to be a
Normative Reference of the new I-D.  Far better if the authors of
RFC7950 had included the procedure for registering a YANG module;
instead, RFC6020 remains a Normative Reference unless and until a YANG
1.2 or YANG 2.0 appears and addresses the problem.

Tom Petch.

Cheers,
Andy
