Yes.

As described in the 03 draft, one possibility is a kind of MIB entry
which only specifies a particular zone (of a particular scope type).
Such a possibility is one of the reasons to adopt this type of format
since the 03 version.

This should be treated as an error, as described in the 03 draft.

Hmm, good question.  I personally think "::" can be treated as a
global scope with regards to the scope architecture, because it does
not cause ambiguity about the "zone".  And, in fact, our current
implementation treats "::" as a global address for convenience, and it
works without anomaly.

Can we agree on this?  Then we'll clarify this point in the next
revision of the draft.
