024 * Editor for {@code java.util.Locale}, to directly populate a Locale property.

026 * <p>Expects the same syntax as Locale's {@code toString}, i.e. language +
027 * optionally country + optionally variant, separated by "_" (e.g. "en", "en_US").
028 * Also accepts spaces as separators, as alternative to underscores.
