Hi Haoyu,

Thank you for your changes.

idnits now reports that the line spacing of one of your figures is =
funny.  I think it is trying to interpret it as text.  This can be =
ignored.

idnits v3 now requests that you have a citation for BCP 14, as you did =
in -03.  You can=E2=80=99t win.  :-). I think that this can also be =
ignored.

Thank you for fixing the reference.

I am waiting to hear back from Carlos regarding his comments and whether =
you have satisfied his objections.

Cheers,
Tony

Please see: =

As you would like people using your bit in a post-stack header to comply =
with that draft, that should probably be a normative reference.
