Language Subtag Registration Form: variant "signed"

[John Cowan]

Doug Ewell scripsit:

Indeed, the current edition of Ethnologue speaks of
Australian Signed English on the Australian SL page
http://www.ethnologue.com/show_language.asp?code=asf .

Before getting formal about it, I'd like to get other input.  To
reiterate, this would look like sgn-US-s-en(-us), and would mean
a signed variety of (American) English using the signs of American SL.
