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.
