Just never occurred to me that it might not be defined, as it is in babel and all other babel-languages I tried seemed to be there.
Could it be an idea to put all available ones on the list on http://wiki.contextgarden.net/Command/language <http://wiki.contextgarden.net/Command/language> and add patterns=... to http://wiki.contextgarden.net/Command/installlanguage ?

Best
Florian.
