For XML, of course, you need to add semicolons to the parameter entity references, and make sure that this is all in the external DTD subset (because of the PEs being used in an ELEMENT decl). You then also have to put your % extended.div.content decl before the ELEMENT div decl. But assuming all this was done, you'd still have to have full control over the mathml and pgml DTDs, to make sure they didn't define any of the same elements as each other - or your Book DTD. It's all one namespace, and XML doesn't allow element redefini- tion. xml-dev: A list for W3C XML Developers. To post, mailto:xml-dev@i...
