I fail to see the logic of that. RFC 3066 is hardly XML/RDF centric. It
isn't even web-centric.
Of course x- tags should be avoided if possible, and at least "none" isn't a
valid RFC 3066 code (nor ISO 639) so there should be no confusion. I would
be a bit nervous of a successor to RFC 3066 allowing 4-letter primary
subtags, and hence leading to confusion.
