May I ask where is the attribute "lang" defined?

In my system there is no "lang" attribute and I was confirmed by another
list (general LDAP discussion list) some months ago that in current LDAP
it's impossible to search only within "default language" (no modifier in
attribute descriptor). Hence I ask for a patch because readily available
solution in my knowledge doesn't exist.
