I think this fails to capture it. What you want is for sequential subtags (extlang and variant) to end in either a concrete tag or a "*". That is, you cannot say "es-Latn-US-*-scouse", but you can say "en-Latn-US-scouse-*". Otherwise certain matching schemes don't work right.

Same for extlangs. In fact, extlangs don't make any sense if you give xx-*-yyy (yyy has to have a very specific prefix, so you have to specify it).

Thus:

Lang = 2*8(ALPHA) / extlang / "*"
Extlang = 0*2("-" 3ALPHA) ["-" 3ALPHA / "*"]

Slightly icky, but essentially correct. I include the "0" here for illustration (it won't appear in the actual ABNF).
