/**
 * The type xsd:language represents a natural language identifier, generally used to indicate the language of a
 * document or a part of a document.  Before creating a new attribute of type xsd:language, consider using the xml:lang
 * attribute that is intended to indicate the natural language of the element and its content.
 *
 * Values of the xsd:language type conform to RFC 3066, Tags for the Identification of Languages.
 * The three most common formats are:
 *
 * For ISO-recognized languages, the format is a two- or three-letter, (usually lowercase) language code that
 * conforms to ISO 639, optionally followed by a hyphen and a two-letter, (usually uppercase) country code that
 * conforms to ISO 3166. For example, en or en-US.
 *
 * For languages registered by the Internet Assigned Numbers Authority (IANA), the format is i-langname, where
 * langname is the registered name.  For example, i-navajo.
 *
 * For unofficial languages, the format is x-langname, where langname is a name of up to eight characters
 * agreed upon by the two parties sharing the document.  For example, x-Newspeak.
 *
 * Any of these three formats may have additional parts, each preceded by a hyphen, which identify additional
 * countries or dialects.  Schema processors will not verify that values of the xsd:language type conform to the above
 * rules. They will simply validate based on the pattern specified for this type.
