Or exceptionally or whatever.  But those codes are not allowed as RFC
3066 subtags, since they are not strictly "alpha-2 country codes from
ISO 3166."  They could be "promoted" to actual country codes, though, if
the Maintenance Agency chose to do so.

If RFC 3066 bis allows the use of M49 codes for a region, it needs to
specify what happens if that region subsequently gets an ISO 3166 code.
