//   Added: 2009-07-29
//   Deprecated: 2010-03-11
//   Preferred-Value: khk

// From CLDR:
//   <languageAlias type="drh" replacement="mn" reason="deprecated"/>
//
// because CLDR also maps macro-languages:
//   <languageAlias type="khk" replacement="mn" reason="macrolanguage"/>

//   <languageAlias type="nld" replacement="nl" reason="overlong"/>
