I didn't state it as a rule, but as true.  Every non-initial 2-letter
tag in RFC 3066 is a country code; the same is true in the draft.
(A private correspondent notes that the reference to "-x-" should
in fact be a reference to any singleton, though "-x-" and "i-" are
the only singletons currently usable.)

It does mean it can't be counted on in the general case.

Section 2.5 (2.4.1 in the draft) states the matching rule in a succinct
fashion.  Everything in 2.4.2 is a non-normative elaboration of this.
