Hi-

I've created an XHTML extension module which validates correctly using the W3C online schema validator, but fails when
I use the .net 1.1 validator.  It seems to be choking on an included W3C file:

     http://www.w3.org/MarkUp/SCHEMA/xhtml-notations-1.xsd

The problem seems to be on this line:

    <xs:notation name="cdata" public="-//W3C//NOTATION XML 1.0: CDATA//EN" />

My code does something like this:

   XmlTextReader reader = new XmlTextReader(new StreamReader(testfile.OpenRead()));
   XmlValidatingReader vreader = new XmlValidatingReader(reader);        
   vreader.ValidationType=System.Xml.ValidationType.Schema;
   vreader.Schemas.Add("http://www.w3.org/1999/xhtml", "http://localhost/TestModule.xsd");

The exception (thrown at the last line)  is this:
 
   System.Xml.Schema.XmlSchemaException : Public attribute '-//W3C//NOTATION XML 1.0: CDATA//EN' is invalid URI. An
error occurred at http://www.w3.org/MarkUp/SCHEMA/xhtml-notations-1.xsd, (31, 4).

Any idea on what might cause that?

Thanks,

-Mike
