Then there will need to be a change in RFC 3066bis, to the effect that
tags that were previously registered under RFC 3066 with the intent of
"registering information about" the tag (second paragraph of Section 3),
and can now (or could then) be composed from valid subtags, are not
necessarily superseded, but maintain their existing informative
registration. (Sorry for the baroque sentence.)
That would allow sgn-US, which can be composed from sgn + US under both
RFC 3066 and RFC 3066bis, to be registered as meaning specifically
"American Sign Language."
I don't know whether this affects only Appendix C or other aspects of
the draft, including the ABNF.
