Re: [Ltru] Prefix bug

Prefixes for variants are NOT required (there is a strong SHOULD and 
multiple suggestions that a variant without a prefix is a Bad Idea). As 
Mark notes, once registered without a prefix, registering *any* prefix 
will break any and all (non-prefix-bearing) tags. However, the stability 
prohibition on narrowing the meaning would seem to be in force.

Validators should not have been required to check variant prefixes, 
given what the working group's intentions were originally. However, I 
very much like firming the registration requirements for variants (from 
SHOULD to MUST on having at least one Prefix) and leaving the validation 
rules in place.

Notice that this would effectively forbid generic variants (the reason 
for the SHOULD in the first place).
