asterisk users - May 2009 - Where are 2 letter language values defined?

I've googled for way too long, where are the 2 letter language values 
defined?

I know:

en = English
es = Spanish
fr = French

but what about Croatian, Russian, Serbian, Vulcan, etc?

Is there a list documented for Asterisk or is it "just use the 2 letter 
country code Internet TLD?"

Thanks in advance,

They are 2-letter ISO country codes.
