Okay, the type "extlang" vs. "language" should be stable.  What if new
subsets are introduced ?  Example:

>From xx-aaa xx-aab xx-aac xx-bbb to xx-aaa xx-aaa-aab xx-aaa-aac xx-bbb

We can't change the "prefix", but we could change the "macrolanguage",
resulting in:

%% Orginal               %% Updated
Extlang:      aac        Extlang:       aac
Prefix:       xx         Prefix:        xx 
Macolanguage: xx         Macrolanguage: aaa

The "extlang" concept is messier than "Suppress-Script", isn't it ?
