This will be the third or fourth try for the document.  Perhaps there is
now enough community interest to make it happen?

Subject: New Version Notification for draft-crocker-dns-attrleaf-07.txt

A new version of I-D, draft-crocker-dns-attrleaf-07.txt
has been successfully submitted by Dave Crocker and posted to the
IETF repository.

Name: draft-crocker-dns-attrleaf
Revision: 07
Title: DNS Scoped Data Through '_Underscore' Attribute Leaves
Document date: 2015-11-14
Group: Individual Submission
Pages: 13

Historically, any DNS RR may occur for any domain name. Recent
additions have defined DNS leaf nodes that contain a reserved node
name, beginning with an underscore. The underscore construct is used
to define a semantic scope for DNS records that are associated with
the parent domain. This specification explores the nature of this
DNS usage and defines the "underscore names" registry with IANA.

Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at
