Why should placing >constraints on the use of PEs be any different? The problem is that this is a relaxation, not a constraint. I want to remove all the arcane rules about where PE's can and can't go and just say they do straight text macro-style substitution, orthogonal to the DTD grammar. But lots of such PE references would be illegal per 8879. With this change, PEs would self-evidently do all the things that PEs do now but would have none of the problems that are making us lean to nuking them. -Tim
