From: Simon St.Laurent <simonstl@s... >No, you don't have the choice of applying _validation_ at whatever level >you like - currently, you have the choice of applying it or not applying it >during the parser. It seems a bit strange to say on the one hand that "XML is too monolithic" and at the same time that namespaces should not be a separate layer and should be folded into the base spec. Which is not to say that it is an impossible view. However, I don't understand the quoted paragraph: who has the choice of validation? The recipient of a document can choose validation only by installing a validating parser; the generator of a document can only choose validation the same way! The instructions needed for a document to *instruct* a system as to what kind of validity may be required are missing from any XML spec: the standalone declaration is advisory. Without such a mechanism, validity cannot be part of schemata: a document cannot assert that it should be valid (according to a DTD or any other schematic) before it is used. I think this is a hole that should be plugged. Rick Jelliffe xml-dev: A list for W3C XML Developers. To post, mailto:xml-dev@i...
