even if they are in the appendix section, it is still true that
your idea does not work. I would like to suggest you to
drop the appendix A from the next revision of the draft.

fair enough, but I really suggest you to drop the section as well,
as it won't work.

you have been saying, in the thread, that the PHB value gets filled
by the originating end. so which is the truth? if the most
significant bit of the flow label field is the indication of
"end-to-end/hop-by-hop", say so in the draft. there's no indication.
