Right, and so we define 'equivalence' between two documents as operationally: 1) parsing two documents produces the same SAX events 2) parsing two documents produces an equivalent DOM object (that's the simple way of saying that these two documents have the same infoset) ok, so the point about validating vs. nonvalidating parsers is a good one and so just tell Bob that if he accepts XML documents from external sources with DOCTYPE definitions, then be sure to use a validating XML parser (or at least one that handles external entities). no fancy wrench needed. -Jonathan
