+Summary: XmlException if XslTransform returns empty document as XmlReader
+Description of Problem:
+XmlException is thrown if XslTransform results in 
+an empty document when using the overload that returns an XmlReader.
+Steps to reproduce the problem:
+using System;
+using System.Xml;
+using System.Xml.Xsl;
+class Test
+        public static void Main(string[] args)
+        {
+                XmlDocument doc = new XmlDocument();
+                doc.LoadXml ("<xsl:transform
+xmlns:xsl='http://www.w3.org/1999/XSL/Transform' version='1.0' />");
+                XslTransform xslt = new XslTransform();
+                xslt.Load(doc, null, null);
+                XmlReader Reader = xslt.Transform(doc, new
+XsltArgumentList(), new XmlUrlResolver());
+                Console.WriteLine(Reader.EOF);
+                Reader.Read();
+                Console.WriteLine(Reader.EOF);
+        }
+Actual Results:
+Unhandled Exception: System.Xml.XmlException: Document element did not
+appear.  Line 1, position 1.
+in <0x0017a> System.Xml.XmlTextReader:Read ()
+in <0x000c3> Test:Main (System.String[] args)
+Expected Results:
+How often does this happen? 
+Additional Information:
+It might not be a bug, but it works under M$.
+Please suggest an alternative method to detect empty result,
+if you think this is the correct behaviour.
