The same as it means in the other dialects.  The semantic conditions for
owl:complementOf don't change - it is always the complement relative to the
class extension of owl:Thing.

In OWL Full, the class extension of owl:Thing is the entire RDF domain, so
complements can be larger than they can be OWL DL.
