I have. I argued that increasingly, both the document and schema will be generated dynamically from relational or object databases. In this situation you would only need to convey the part of the schema needed to validate the part of the 'document' passed. It therefore seems inconceivable to me that you would need to pass a 100k schema for a 1k document - you just pass a 'sub-set' of the schema (which is still itself a valid schema). An exception would be if you were allowing the recipient to edit the document, but even then you could incrementally pass the parts of the schema that were needed for the area being edited, so that the target application gradually built up the full schema as and when it needed it - a clear advantage to me of using XML for everything, including expressing XML. (I have devised a working prototype of this, in case people are thinking it's too complicated.) Regards, Mark Birbeck http://www/iedigital.net/ xml-dev: A list for W3C XML Developers.
