About intersection in Lite, the Reference now includes in Sect. 8.3 the following text fragment for types of "class axioms" allowed in Lite: > 3. Class axioms that consist of a class description of the owl: > intersectionOf type, with a class identifier as the domain > value of the intersection statement. The range should be a > list of class identifiers and/or property restrictions. I think this is what we decoded and it is consistent with the OWL Lite class axioms in AS&S (Sec. 2.3.1.1, the "complete" class with multiple "supers", which leads to a syntactic form that is covered by the second mapping rule for classes in Sec. 4.1) Guus Deborah McGuinness wrote: > > > "Peter F.
