Folks,

While we have the attention of DNSOP folks this week, I'd like to ask for
review of this draft (I meant to send it earlier in time for f2f discussion
on Tuesday, but better late than never).

    https://datatracker.ietf.org/doc/html/draft-huque-dnsop-blacklies-ent-01

Excerpt:

               Empty Non-Terminal Sentinel for Black Lies

Abstract

   The Black Lies method of providing compact DNSSEC denial of existence
   proofs has some operational implications.  Depending on the specific
   implementation, it may provide no way to reliably distinguish Empty
   Non-Terminal names from names that actually do not exist.  This draft
   describes the use of a synthetic DNS resource record type to act as
   an explicit signal for Empty Non-Terminal names and which is conveyed
   in an NSEC type bitmap.

[...]

Thanks!
Shumon.
