RE: Flipped locations between d11 and d12.

[Black_David@emc.com]

The new notation has a long history of use in networking
specifications and is required (not just "preferred")
in all IETF standards-track RFCs.  See the
"Bit and Byte order in drawings" Section of

http://www.ietf.org/ID-nits.html

It's unfortunate that we caught the need to make this
change relatively late in the process, but the change
does need to be made ... otherwise the draft will be
returned to the WG with instructions to make the change.

Thanks,
--David
