I think it would be nice if the "most specific" version availible is choosen.
something like:

1.) for every preferred language of the client check in order of preference:
2.) if language has form xx-yy check if xx-yy.msg is availible. if not
check if xx.msg is availible.
3.) if both in 2.) are not availible, check for next prefferred
language. if no more langs are availible use the default language.
