| IPv4 mapped address must not appear on wire,
| in any of IPv6 header fields, extension header fields, or payloads
I'm sure you didn't really mean that, as that would be going way too
far.
That is, you aren't seriously prohibiting any data that happens to
be 80 bits of zeroes, followed by 16 bits of ones, followed by
32 bits of something else, from ever appearing in a packet payload
are you? Or even as a data pattern that might happen to occur in
some IP header (perhaps encryption data in the ESP header).
I have no problems with prohibiting them in address fields in IPv6
headers ("the" IPv6 header, and the others that contain addresses),
but anywhere else, the IPv6 address architecture doc has no business
treading.
So, make that "in any address fields of the IPv6 header, or extension
headers"
