Yes, and this is one of the things that I think distinguishes our closed-world success story from scaling this concept to the Web. In many cases we were able to solve "web of trust" type problems through policy.
However, I think that once you simplify the problem to classifications, you also simplify the authority problem, because the level of authoritativeness just becomes a meta-classification, and can be operated on using the same class of automata as those that operate on the rest of the ontology. I think that if such ontologies can scale to the Web at all, that they will be able to handle classifications of authority.
