If we make the internal subset simple enough, we could even require parsers to read ATTLISTs for defaulted and fixed values. From there it is just a hop, skip and a jump to architectures. > The idea is, even if PE's > are agreed to be necessary for validating applications, I can > see no good argument that a lightweight DTD-less WF doc > reader should ever have to deal with them.

Language lawyers? The proposed WebSGML changes to SGML are so massive that PE generalization doesn't seem outrageous to ask -- if it is a good idea. Paul Prescod
