Hoi,
mn is the code ISO-639 for the language, Mong is the CLDR code for the script and CN is a code for the country where it is practices. The correct LANGUAGE code is either khk or mvf because as a macro language that does not have an existing project it is not eligible.
Thanks,
     GerardM

I wonder about the upper casing. I can not find much information about this "language" code. It appears it is not a language, but Mongolian (mn) written in a specific script. I do find information about a "mn-Mong-CN" tag. What's the difference? What's the correct tag and in which standard is it defined? Which casing is the correct one?
