OK, after reading the discussion, my opinion, as an author (but I'll
of course defer the decision to the working group, the WG chairs, the
RFC editor and the flying spaghetti monster):

The re-definition of QNAME by RFC 2308 is awkward and does not match
the general usage, or the previous definitions. Therefore, I prefer to
keep the "common sense" usage "QNAME is the owner name of the record
in the Question Section". Which means that, in my example, the QNAME
is "www.afnic.fr" and the current text of
draft-ietf-dnsop-nxdomain-cut-05 is correct.
