Well, I object to drawing anyone's attention to the Appendix of
2460, which is explicitly not part of the standard. And I think
that the main text in 2460 is underspecified, whereas RFC 3697
has proved to be plain confusing. And we don't yet have clear
consenus on 3697bis. Does all this belong in a requirements list?
