Summary: This document is ready for publication as a proposed standard.

I do have two questions that I hope has already been considered by the WG and
is a non-issue.  See minor issues.

Major issues:

Minor issues:
1) I presume IANA has been involved in the development of this document, and is
willing to undertake the maintenance?  I looked for but did not see where that
was noted. 2) I question the use of enumerations for the content.  I understand
that since IANA will generate new YANG modules when there is a change, the new
models can have new values.  I am concerned that if an implementation using the
older schema reads data from a DNS repository with updated entries (and the
corresponding updated version) the version skew will cause processing errors
instead of simply handing over the numeric value in a fashion that is
acceptable but not understood.
