See:

Brief summary (even if you dump datatype groups, which were not intended to be part of OWL 1.1; this should be clarified): N-ary datatypes seem both fragile and wrongly expressive (as compared, e.g., to dl-safe rules with built-ins). The key example is unit conversions.

Comment 1 by bparsia, Mar 29, 2007

Also, there are no built-in n-ary datatypes, nor a language for defining them. E.g., see:
