Grandfathered tags.

Prior to RFC 4646, whole language tags were registered according to the rules in RFC 1766 and/or RFC 3066. All of these registered tags remain valid as language tags. Many of these registered tags were made redundant by the advent of either RFC 4646 or RFC 5646. The remainder of the previously registered tags are "grandfathered", and are all veriants of this enum type.
