[dnsext] WG opinion on draft : Improvements to DNS Resolvers, for Resiliency, Robustness, and Responsiveness

[Olafur Gudmundsson <[e-mail]>]

The chairs have received a request to Last call this draft.
http://tools.ietf.org/html/draft-vixie-dnsext-resimprove-00

This draft is clearly in scope of the Working Group.

As there has not been much discussion on this draft the chairs are
not ready at this point to start a Last Call but would like to get a 
sense of the working group participants' feelings on the draft.

The draft is aimed at BCP status; thus there is no RFC2119 language in 
the draft.

Background: The draft contains three recommendation on how resolvers 
operate,
     A. Re-validating a delegation when a parent NS RRset TTL expires.
     B. Stopping a downward cache search when an NXDOMAIN is encountered.
     C. Upgrading the credibility of NS RRsets upon delegation event.

All of these have been suggested in various forms over the years.

Following opinions are sought:
1. Are the suggestions in the draft something people think is a good
    idea?

2. Is the draft clear in its message?  If not, please suggest improvements.

3. After (if any) editing fixes is this draft ready for WG Last Call?
