I assume you mean you’re only allowed to add 2- or 3-letter language 
codes from ISO 639. What other features of BCP 47 does the XKB 
specification not support?

If someone or some organization claims to support “language tags” but in 
fact only supports 2- or 3-letter ISO 639 language codes, with or 
without 2-letter ISO 3166-1 region codes, no script subtags or variants 
or what not, then the right thing to do is to educate them about BCP 47 
and try to persuade them to migrate.

That, of course, assumes that the specification is not frozen. Wikipedia 
seems to think the latest stable version of XKB is from 1996. There's 
not much you can do about such things, and it doesn’t mean time has to 
stand still for everyone else.
