Validation fails when mixing XSD and DTD

[ben]

When running the code below the validation fails when the first line of
my xml contains

<legalEnvelop e version="1.1"
xmlns:xsd="http ://www.w3.org/2001/XMLSchema"
xmlns:xsi="http ://www.w3.org/2001/XMLSchema-instance" >

If I change this line to

<legalEnvelop e version="1.1">

It validated fine.

Anyone have any idea why this is?

The exact error this throws is:
An unhandled exception of type 'System.Xml.Sch ema.XmlSchemaEx ception'
occurred in system.xml.dll
Additional information: System error.

===========CODE =============== ===
XmlValidatingRe ader myVReader = null;

xd.LoadXml(LNSe a.IO.FileHelper .FileToString(f ));

string myRootNodeName = xd.DocumentElem ent.Name; //
this.DocumentEl ement.Name;
XmlDocument myNewDom = new XmlDocument();

myNewDom.Append Child(
myNewDom.Create DocumentType(my RootNodeName,nu ll,dtdFileName, null));
myNewDom.Append Child(myNewDom. ImportNode(xd.D ocumentElement, true));

myVReader = new XmlValidatingRe ader(new XmlTextReader(n ew
StringReader(my NewDom.InnerXml )));

myVReader.Valid ationType = ValidationType. DTD;
while(myVReader .Read());

Could you attached a validation event handler to the validating reader,
which catches the XmlSchemaExcept ion and also find out the message, line
number, line position which caused it?

Thanks.
