Re: [nfsv4] Review of draft-ietf-nfsv4-rfc5661sesqui-msns-01

[David Noveck <[e-mail]>]

I now have an rfc5661sesqui-msns-02 ready to go and will submit it whenever
that is appropriate.  This addresses your review comments and deals with
the errata issue by revising sesqui to include 2006 (with some
clarifications) and explaining that the rest of the errata are to be
addressed as part of rfc5661bis.
