/**
 * @type LocaleCode
 * A descriptor for a geographical region by both a language and country code. By combining these two, regional differences in a language can be addressed, such as with the request header parameter `Accept-Language` following [RFC 2616](https://tools.ietf.org/html/rfc2616) & [RFC 1766](https://tools.ietf.org/html/rfc1766). This can also just refer to a language code, also RFC 2616/1766 compliant, as a default if there is no specific match for a country. Finally, can also be used to define default behavior if there is no locale specified.
