One place to see the problem is in KIF. The KIF definition http://logic.stanford.edu/kif/dpans.html gives an example where a truth predicate can cause problems. In the DAML+OIL area, if you require the presence of all syntax-like constructs in the semantics you can easily end up with structures like :_x complementOf :_x . in all interpretations. Now consider whether :_x is an instance of :_x. peter
