Quoth the XML Rec: "For compatibility, it is an error if an element in the document can match more than one occurrence of an element type in the content model. For more information, see E Deterministic Content Models." > Elliotte:> No conforming validating XML parser will reject [ambiguous > Elliotte:> content models]. > Rob Lugt:> This long-winded sentence appears to be referring to deterministic > Rob Lugt:> content models. In addition it indicates that the constraint should > Rob Lugt:> be treated as an *error*, not a warning. You are both wrong, alas. "It is an error" means that 1) no XML document should do this, and 2) an XML processor may or may not detect or report it. So the use of an ambiguous (non-deterministic) content model may cause any of the following behaviors: 1) it just works; 2) it just fails silently; 3) it just generates an error; 4) it just makes demons fly out of your nose. -- Not to perambulate || John Cowan <jcowan@r...> the corridors || http://www.reutershealth.com during the hours of repose || http://www.ccil.org/~cowan in the boots of ascension. \\ Sign in Austrian ski-resort hotel
