I think, removing references like "valid" or "validity" from XML spec is a good idea. I think, this makes good distinct architectural layerings like pure XML markup and document validity. It seems, that most people argue that a conformant XML document has ability to refer to user defined entities, and this can be specified only in a DTD. I think, the current XML spec, makes DTDs an inseparable part of XML spec is, because of the DTDs ability to specify user defined entities, which (the entities) are part of say the, XML 1.0 (and 1.1) spec. To change the XML spec, to remove the concept of valid/validity and being able to remove DTD s from the XML spec, I think will also require us to remove the concepts of entities from the XML spec (I think, something like a future XML 2.0 spec should only specify the built in entities like & amp; etc and not allow users to specify user defined entities, unless they use an external thing like DTD or a future XSD (a 1.2 version, which may allow users to specify entities, via some global declaration perhaps)). -- Regards, Mukul Gandhi
