I was thinking how to parse "XX_YY-Z" variant. Since it is not well-formed
subtags in BCP 47 definition, it should be delimited by `_` so there would be
two values, "XX" and "YY-Z" according to the current spec. However, I
understand that the implementation treats '_' and '-' equally both for
well-formed and ill-formed variant values, I think it's better to put
`separated by ('_'|'-')` to remedy the spec.
