A very quick and easy find on OWL S&AS results in:

Definition: The disallowed vocabulary from RDF is rdf:type,
rdf:Property, rdf:nil, rdf:List, rdf:first, rdf:rest, rdfs:domain,
rdfs:range, rdfs:Resource, rdfs:Datatype, rdfs:Class, rdfs:subClassOf,
rdfs:subPropertyOf, rdfs:member, rdfs:Container and
rdfs:ContainerMembershipProperty. The disallowed vocabulary from OWL is
owl:AllDifferent, owl:allValuesFrom, owl:AnnotationProperty,
owl:cardinality, owl:Class, owl:complementOf, owl:DataRange,
owl:DatatypeProperty, owl:DeprecatedClass, owl:DeprecatedProperty,
owl:differentFrom, owl:disjointWith, owl:distinctMembers,
owl:equivalentClass, owl:equivalentProperty, owl:FunctionalProperty,
owl:hasValue, owl:intersectionOf, owl:InverseFunctionalProperty,
owl:inverseOf, owl:maxCardinality, owl:minCardinality,
owl:ObjectProperty, owl:oneOf, owl:onProperty, owl:Ontology,
owl:OntologyProperty, owl:Restriction, owl:sameAs, owl:someValuesFrom,
owl:SymmetricProperty, owl:TransitiveProperty, and owl:unionOf. The
disallowed vocabulary is the union of the disallowed vocabulary from RDF
and the disallowed vocabulary from OWL.  

The change would be from listing the disallowed vocabulary in the RDF,
RDFS, XSD, and OWL vocabulary spaces and allowing all other to
effectively listing the allowed vocabulary from these spaces and
disallowing all other.  So, for example, owl:class was allowed in OWL 1
but would not be allowed under this proposal.
