Subject:XML Schema converted to DTD Author:Ted White Date:20 Aug 2001 03:47 PM
I recently defined an XML schema and saved it to a .xsd file. Then I created an XML document conforming to that schema and attempted to verify that the XML document conformed to the schema. I was prompted to use an internal or external DTD, chose external and selected the .xsd file saved previously. The .xsd was somehow translated to a DTD and saved back to the original file in DTD format. My question is whether Stylus Studio does that conversion on purpose? If so, why allow the creation of .xsd files?

When you asked Stylus Studio to create an external DTD and entered the name
of your .xsd file, Stylus Studio created a DTD reading the XML document you
had opened. It didn't convert the .xsd file to anything; it just overwrote it.
XMLSchema validation was not available in 3.0; it is in 3.1 Beta 1 (with a
few limitations), which is being made available as we speak.
XMLSchema has become a W3C recommendation early this year; Stylus Studio
has started supporting it from the beginning (through its editor), but the
XML parser on which we rely (Apache Xerces) has made initial XMLSchema
support available only a couple of months ago. XMLSchema validation relies
on the Xerces module.

Yes; but you have to create the grammar to attach the XMLSchema to your XML
document manually (an "attach dtd/XMLSChema to..." will be available in
next builds).
So, you will have to manually create something like:
xsi:noNamespaceSchemaLocation="c:\myschema.xsd">
....
