xml-dev - XML Schemas

[Veena Rao <veena@persistence.com>]

In all the XML examples that I have come across, I see that
there is a .xsd defined and referenced in the examples. Each
example uses a schema definition (.xsd) specific to that example.

Is it always necessary to use and specify a XML Schema in an
XML document that needs to be parsed. Won't it be sufficient to
have it validated against a XMLSchema DTD.

I am trying to find out if I can get away without generating a .xsd
for every object model that is used within our application server.

Any expert opinion on this is very much appreciated.

Thanks, Veena
