XslCompiledTransform and document() function - 16 July 2007

XslCompiledTransform.Transform appears to be trying to validate documents
I load indirectly via the document() function.

I only want to validate my source XML document against my schema. My
XSL code simply calls document("c:/RefDoc.xml") to look up data in an
external table. I don't really want to validate RefDoc.xml, though I don't mind
doing so if I can tell it which schema to use.

Here is my code (C# 2.0):

public class XsltTransform
{
   private string m_schemaValidationErrors = "";
   public XsltTransform() {}

   public void transform(string sourcePath, string schemaPath, string xsltPath, string resultPath)
{
      try
    {
         // Set up an XmlReader to read the source XML document.
         XmlReaderSettings settings = new XmlReaderSettings();
         settings.ConformanceLevel = ConformanceLevel.Auto;
         settings.IgnoreWhitespace = true;
         settings.IgnoreComments = true;
                // Removing the following 3 statements allows it to run w/o validation.
         settings.Schemas.Add(null, schemaPath);
         settings.ValidationType = ValidationType.Schema;
         settings.ValidationEventHandler +=
            new ValidationEventHandler(settings_ValidationEventHandler);
         XmlReader reader = XmlReader.Create(sourcePath, settings);

         // Set up a processor to run the XSL transform.
         // Since the XSLT code uses the "document()" function, enable that.
         // Also, for the same reason, we need an XmlResolver.
         XsltSettings xsltSettings = new XsltSettings();
         xsltSettings.EnableDocumentFunction = true;
         XmlUrlResolver xur = new XmlUrlResolver();
         XslCompiledTransform myXslTransform = new XslCompiledTransform();
         myXslTransform.Load(xsltPath, xsltSettings, xur);

         // Now, perform the transform.
         XmlTextWriter writer = new XmlTextWriter(resultPath, null);
         myXslTransform.Transform(reader, null, writer, xur);
         writer.Close();
    }
      catch (Exception e)
    {
       System.Console.WriteLine(e);
    }
}

   void settings_ValidationEventHandler(object sender, ValidationEventArgs e)
{
    m_schemaValidationErrors += e.Message;
}
}

The error I am getting is: System.Xml.Xsl.XslTransformException: An error occurred
while loading document 'RefDoc.xml'. See InnerException for a complete description
of the error. ---> System.Xml.Schema.XmlSchemaValidationException: The 'RefDocRoot'
element is not declared.
