I think strictly speaking both OWL and RDFS only add information, but
with OWL you can at least check that the information is logically
consistent and use to validation in some sense. I think to use domain
and range to get validation you really need OWL disjoints as well. I
guess in theory you could check the inferred types for instances based
on the range/domain restriction but that could be pretty tedious for a
large abox!?
