Lets stop the discussion whether an IPv6 address plus scope-identifier
is some sort of an address or not.
I think the proposed TC is clear what the sematics of the bytes are on
the wire and I expect that managers and agents will be implemented to
do the right thing with it. So lets know fight about whether this is
an address or not.

Can you summarize the reasoning why the scope identifier should be in
front of the IPv6 address? Why does <address>%<scope-id> not work?

Perhaps it is a sign that IPng folks need to agree a little bit faster. ;-)
