I guess that the XML document you were validating was using the xsi:noNamespaceSchemaLocation="email.xsd" attribute to specify where the schema file was. And now you are using email.xsd as a normal XML file, so you need to tell the parser where its schema is. >And one more question: in case that I really do have to specify that >schema location, would it be possible to do it in schema syntax rather >than in the DTD syntax that you proposed?

I think that schemas are >good enough not to have to depend on DTDs, aren't they? :-) The problem is, last time I tried to use the XMLSchema.xsd schema to validate an XML Schema file, I got a ton of errors (bug 7417, http://nagoya.apache.org/bugzilla/show_bug.cgi?id=7417 ): for instance XMLSchema.xsd defines xsd:anySimpleType, but Xerces doesn't allow its (re)definition. The other solution (that I use when I need to validate an XML Schema), is to use the "parser that is built in", as you say. You just need a valid email.xml file that points to email.xsd; if validation fails, there is an error inside the XML Schema.
