in any one of these forms lang					lang-variant lang-script				lang-script-variant lang-region				lang-region-variant lang-script-region		lang-script-region-variant each of lang, script, region, and variant, when used, must be valid

For templates, the parameters |script=, |region=, and |variant= are supported (not supported in because those parameters are superfluous to the IETF subtags in |code=)

returns four values. Valid parts are returned as themselves; omitted parts are returned as empty strings, invalid parts are returned as nil.
