OWL DL (and OWL Lite) does /not/ allow the use of RDF lists as /semantic
entities/, that is, you cannot use lists in statements like
ex:journey ex:visitedCities ( ex:Berlin ex:London ex:Paris ) .
OWL DL uses RDF lists as part of the RDF encoding of its syntactic
constructs. For example, an intersection of classes is encoded by something
like
_:x rdf:type owl:Class .
_:x owl:intersectionOf ( :c1 :c2 ) .
So lists may only occur in these well-defined contexts. Every other use of
RDF lists is disallowed in OWL DL.
