Wrong, wrong and wrong again. This is getting tiresome.

IMHO, the dynamic topologies can not have its control-messages mixed in one same packet. The draft restricts that each topology has one-metric-type, but does not restrict its control-packets, that is why we need a section about packets to fix that. I will review the related drafts again to write down the full conditions for this draft.
