	 * is technically dual, but in practice it's used as plural.
	 * In some cases, usually with expressions of time, three forms
	 * are needed - singular, dual and plural.
	 * CLDR also specifies a fourth form for multiples of 10,
	 * which is very rare. It also has a mistake, because
	 * the number 10 itself is supposed to be just plural,
	 * so currently it's overridden in MediaWiki.
