I am thinking an open registry with moderation by knowledgeable persons.

I imagine that browser vendors would willingly adopt registered  
language tags in addition to the set they currently support. I  
envisage that those that register a language tag would have a real/ 
innovative need/application for that language tag. The language tag  
registry would guide the browser vendors and form a reference source  
for applied language tags.

Thank you for that info. Interesting and illuminating.

I am using firefox and currently there are only the standard (not sure  
who's standard :-)) language tags available for user selection. So,  
currently, it is not just a matter of setting browser preferences.  
When I want a different language tag then I use the firefox extension  
"Modify Headers" to change the http header Accept-Language. I  
currently have Modify Headers set up for en-Brai, zh-Brai, ja-Brai, ko- 
Brai (for my experimentation with adaptive websites) which are not  
available in the firefox set of language tags.

So, if, for example :-

I were to register ja-Brai in a language tag registry and if browser  
vendors were to incorporate those language tags in the registry then  
ja-Brai would be user selectable by all users.
