Who would be allowed to register there? How could we force browser 
vendors to follow this registry?

Please note that draft-ietf-ltru-4645bis deprecates codes such as sgn-GB 
in favor of ISO 639-3 three-letter codes (gss for sgn-GB).

Why would this be helped by having an accepted list of languages for the 
browsers? Even without that, you can set your browser's preference to 
include jsl (sgn-JP), and if that's available on signtube, it can easily 
be served. The big obstacle to that is not an uniform list in the 
browser, but the cost of translation.

Regards,    Martin.
