No. I think it was a way of saying something simple and familiar will work until something more precise and powerful can replace it. It was a stabilizer in a time of incredible shifts and unpredictable fortunes. It's clear that validity is not intrinsic to markup functionally. It is just as clear that validation is useful to applications. We let the next thing go too far in terms of application. We needed multiple validators for different users and uses. We have that now but also we have entrenched factions of users. len -----Original Message----- From: Mukul Gandhi [mailto:gandhi.mukul@g...] Sent: Saturday, November 07, 2009 9:25 AM To: Michael Sokolov Cc: Michael Kay; xml-dev@l...

I think, presence of DTD in the XML spec exactly says this (i.e, validity is a concept inseparably tied to XML markup). But of course, XML document validity is optional for applications to perform. Since DTD is already mentioned in the XML spec, why not specify XSD as well as a normative reference to a future XML spec? I think, even an errata to a current XML spec can fix this. I am not sure, if another edition of XML is underway [1]. If that's [1] happening at W3C at the moment, it may even contain this normative reference I am suggesting. Even W3C says, that XSD replaces DTD as a better XML validation technology. And XSD 1.0 version has been in existence since many years now, and implemented by quite a few XML products, and also deployed widely in end user applications. Therefore, why XML standard cannot say that XSD is a validation technology like what DTD is? I think, mentioning XSD in the XML spec will encourage users to use XSD as a better validation technology, than DTD. Mentioning this as a reference link in XML spec, looks like a very minor and non disruptive addition to me, for the XML spec. -- Regards, Mukul Gandhi _______________________________________________________________________ XML-DEV is a publicly archived, unmoderated list hosted by OASIS to support XML implementation and development.
