>And a *lot* of people are writing apps that read in XML right now today; I wonder how many of them are including an XSD valudation step? -Tim Indeed, not many I would think. Truth is that many developers / teams choose for XML as the communication language between various components of their application which they all write themselves. And why would you use validation in such a case ? You know perfectly well which XML is being generated ... it's not going to change overnight. One side on the app generates and the other side receives (and vice-versa) ... no need for a DTD or XSD. Agreed ?

Point being that I see quite a lot of this kind of stuff having to be done wherever the data is important and then finally the XSDL gets added in basically checking that structure is right. ----------------------------------------------------------------- The xml-dev list is sponsored by XML.org <http://www.xml.org>, an initiative of OASIS <http://www.oasis-open.org> The list archives are at http://lists.xml.org/archives/xml-dev/ To subscribe or unsubscribe from this list use the subscription manager: <http://lists.xml.org/ob/adm.pl>
