Isn't a violation of the stability principle? (Yes, the > "extlang" production in RFC 4646 was marked as "reserved for future > use" but it was legal nevertheless.) Correct. Since there have never been registered extlang subtags, there might be parsers that allow for it but there should not be any tags that include them. If some such tags are out there in the wild, they would be well-formed but not valid in 4646, and neither well-formed nor valid in 4646bis (under this proposal).
