Hi Vijay,

I will give a review on S6 and S7 by Wednesday.

Sabine: Thank you for getting this out.  I was hoping that all nits
identified by IDNits tool will be taken care in this revision.
Unfortunately, IDNits reports three warnings for -06.  These need to be
eventually fixed, perhaps as part of Auth-48, etc.

But before I can send the draft to IESG, I need key members of the WG
who have reviewed previous versions of this draft to review the newly
added Security Considerations section.  You only need to review this
section, as previous versions of the draft were reviewed in their
entirety.  The new addition here is S6 (Security Considerations) and S7
(Operations Considerations).

Can I please request a subset of the following people to review S6 and S7:

   Yichen Qian, Li Geng, Dawn Chen, and Jensen Zhang

I will like at least two people from the above set to read S6 and S7 and
let the WG know whether the draft is ready to be moved out of the WG.

Please do so soon, preferably by Wed midnight (US Eastern).  The
sections are short, but your reading and feedback to the WG will be

Thank you,
