If you were a citizen of Austria or Switzerlad, you would not be able to use \mainlanguage[at] or \mainlanguage[ch]
As it happens, "at" is not the ISO 639 code of any language (and it's doubtful it will be in the near future), but "ch" is the code for Chamorro (http://www.ethnologue.com/show_language.asp?code=cha), so you would indeed have problems :-) Arthur
