[Koha] UDC and sign language

[Ramon Andinach]

Ok, actual library question this time.

This is for anyone out there that handles UDC cataloguing. We've got a  
copy of the abridged edition, and so far it's handled just about  
anything we've thrown at it, except this:
Where does sign language (e.g. ASL, AUSLAN, NZSL etc) fit into the  
languages?

I can't find it (or braille for that matter) in the Common Auxiliaries  
of Language anywhere!
