Correct. (latest draft is Oct. 22 1999, see
draft-ietf-mobileip-ipv6-09.txt, chapter 5)

I guess either those values were different at the time or the
programmers used other values as they sent UDP packets for that matter.

Destination Options are still not implemented in the IPv6 Linux kernel
(2.2.13 or 2.3.31), hence there's no Binding Update Option available
without a hack.
I would like to have your opinion (all) on that:
shall we keep on using UDP or is it an option to actually implement the
Destination Options in the IPv6 Linux kernel (which has already greatly
improved since 2.1.59)?
As a complementary question, what is your view on the complexity of the
DestOpt implementation?
