+ *
+ * * _languageCode_: The language code used for the `lang` attribute in ISO 639 format.
+ * 	Language codes can be found [here](http://www.loc.gov/standards/iso639-2/php/English_list.php).
+ * 	You can use both 2-letter ISO-639-1 codes and 3-letter ISO-639-2 codes, though
+ * 	for consistency it is recommended to stick to ISO-639-1 2-letter codes.
+ * * _languageLabel_: The label to show for this language in the list.
+ * * _textDirection_: (optional) One of the following values: `rtl` or `ltr`,
+ * 	indicating the reading direction of the language. Defaults to `ltr`.
