We were waiting for one person who provided document review to
respond to the authors. The shepherd decided to go ahead and proceed with
publication regardless since the individual was a little hard to get hold
of over the last few months. There is still an opportunity on the IETF
wide last call; the shepherd will communicate with the person to make

11) Identify any ID nits the Document Shepherd has found in this
document. (See http://www.ietf.org/tools/idnits/ and the Internet-Drafts

There are a few minor warning nits that could be fixed before
publication. There are of two types:
a) "weird spacing"
b) "unused reference"
c) Not found by the nits tool is the fact that section 3.1
on line 261, a reference to RFC5812 is made when it should be
a reference to RFC1812 (only off by 4000;->).
(12) Describe how the document meets any required formal review criteria,
such as the MIB Doctor, media type, and URI type reviews.

normative or informative?
All references are properly separated and labelled.

makes are associated with the appropriate reservations in IANA registries.

Confirm that newly created IANA registries include a detailed
specification of the initial contents for the registry, that allocations
procedures for future registrations are defined, and a reasonable name
for the new registry has been suggested (see RFC 5226).

introduces new registeries.
It adds definitions to LFB Class Names and LFB Class Identifiers
It adds 3 new registeries for holding:
a) Metadata ID, b) Exception ID and c) Validate Error ID.
(18) List any new IANA registries that require Expert Review for future
