The case against internal subsets is compelling IMHO. They don't round trip. This creates significant problems for software developers working with hetrogenous, loosely coupled XML processing systems. i.e. anything other than XML "viewers". I have droned on about this for years now and will spare everyone a replay[1] :-) I believe (correct me if I'm wrong James) that James Clark is referring to this problem when he says of the internal subset approach to this problem ([2]) "(iii) It doesn't work with streaming output. This is in my view the most important technical problem" regards, Sean [1]http://lists.xml.org/archives/xml-dev/200109/msg00722.html [2] http://lists.xml.org/archives/xml-dev/200111/msg00461.html
