I have a great deal of respect for your views, and I don't think you're wrong here per se. While I agree with what you've inferred about the standard, I'm not at all certain that the standard itself forces your interpretation. In the above case, for example, the standard is talking about well-formed docu- ments as if all parsed entities must be read in if used in the document. In fact, this is not a requirement. The whole reason parameter entities, e.g., are not supposed to be used inside markup in the internal DTD sub- set is that this allows us to bypass them if you're not validating. (Incidentally, does it bother anyone else that you can have valid docu- ments that aren't well-formed? Imagine an external entity used inside an attribute value? If declared in such a way that a non-validating parser doesn't realize it's external, then the validating parser will reject it as an error (can't have external entities in this context). There are other such cases, although this is the main one that comes to mind.) My general point is that the question of what you do while validating is not simply a superset of what you do when just parsing with well-formed- ness in mind. You process documents in somewhat different ways depending on which of these two alternatives you've chosen. And so the question of what context an external entity should be checked in, if validating, is not clearly answered from the spec without exegesis, and I would ar- gue, background knowledge. Anyway, even if I grant that it says what you want it to, then the point should still be made that it does so in a way that's not easy to interpret or understand. The fact that the writers of IE's parser apparently got it wrong is therefore not at all unexpected. -- Richard Goerwitz PGP key fingerprint: C1 3E F4 23 7C 33 51 8D 3B 88 53 57 56 0D 38 A0 For more info (mail, phone, fax no.): finger richard@g... xml-dev: A list for W3C XML Developers.
