I don't see why the charter should explicitly mention that the
addressing model should work with manual and static routes. As Teco
said, this would be part of the solution space, i.e. it could be part of
a draft that describes an autoconf mechanism.

Well, as said, I don't think that's part of the discussion we lead here
concerning the charter.

Yes, but I don't think it should be mentioned in the charter. The
charter does not say anything that the addressing model should have any
preconditions for a particular MANET routing protocol. Otherwise, it
would need to list a large number of routing protocols (OLSR, OLSRv2,
OSPF, AODV,....)

I agree with Teco. MANETs can run on a number of different L2
technologies with certain characteristics. These characteristics should
be mentioned in the document to be written, but not in the charter. In
my opinion, no specific L2 should be mentioned.
