With my WG chair hat off, I think the document more or less satisfies
the requirements. The only two change I would suggest to make are (a) to
eliminate a special case for Withdrawn Routes (this is based on
some discussion that happened few years ago initiated by Pedro Marques),
and (b) explicitly spell out that an implementation SHOULD/MUST allow
to configure MRAI to 0.
