The punning feature in OWL2 is very nice indeed. But one should not
forget that depending on the use the subject (or object) is either the
class *or* the instance. I.e., there is a "class view" of the resource
identified by the URI, and an instance view. This is different from
referring to a class as an instance. So things you say about the URI
using object properties you say about the instance identified by that
URI, just as you would if you used a generated instance URI, and the
rules that apply to that are no different from the rules that apply if
you said those things about an instance with a randomly generated URI.
For example, if you say conflicting things about it, you still say
these about one and the same instance, not "some", possibly different,
