Hi Brian, Melinda,
I forgot to mention that feedback should be sent to the ietf(_at_)ietf(_dot_)org
mailing list. Please use the existing thread (
https://www.ietf.org/mail-archive/web/ietf/current/msg99765.html ).
Speaking for myself, I am okay with negative criticism on this thread.
Regards,
S. Moonesamy
