Description

In HTL the @​i18n tag fails when jcr:language not in ISO list.
es_PY falls back to es, but es_XL falls back to default en.

I think this is related to the check for valid countries in JcrResourceBundleProvider::toLocale().
If you feel you must check for valid country code, please also allow case where country code starts with X which is allowed by the [IANA spec](https://www.iana.org/assignments/language-subtag-registry/language-subtag-registry).
