- proper status of this document (info vs. BCP) and whether this
document can update any existing RFC
There's a standards-track beast defined in section 3.2 of RFC2026 as
an
"Applicability Statement":
" An Applicability Statement specifies how, and under what
circumstances, one or more TSs [technical specifications] may be
applied to support a particular
Internet capability.
...
An AS also specifies the circumstances in which the use
of a particular TS is required, recommended, or elective..."
I think we can choose, if we want, to make the present document
an "Applicability Statement" Proposed Standard or BCP that describes
the functionality of a full-spec IPv6 node, and therefore elevates
MAY to SHOULD or MUST if we want to.
Personally, I think that's a good idea, rather than issuing an
informational
document that leaves wiggle room on basics such as ND.
