+Summary: improper handling of xml declaration in XmlTextReader and NodeType.Element 
+
+Description of Problem:
+1. If you pass an xml fragment that contains an xml declaration with
+anything but version and encoding attributes, you get an exception.
+2. XmlTextReader skips the xml declaration (might not be a bug, but M$
+behaves differently)
+
+Steps to reproduce the problem:
+using System;
+using System.Xml;
+
+class Test
+{
+        public static void Main(string[] args)
+        {
+                string xml = "<?xml version='1.0' encoding='utf-8'
+standalone='yes'?><root/>";
+                XmlReader Reader = new XmlTextReader(xml,
+XmlNodeType.Element, null);
+                Reader.Read();
+                Console.WriteLine(Reader.NodeType);
+        }
+}
+
+Actual Results:
+Unhandled Exception: System.Xml.XmlException: expected '?' (3F) but found
+'s' (73)
+in <0x0017c> System.Xml.XmlTextReader:Expect (Int32 expected)
+in <0x00036> System.Xml.XmlTextReader:Expect (System.String expected)
+in <0x00321> System.Xml.XmlTextReader:SkipTextDeclaration ()
+in <0x00220> System.Xml.XmlTextReader:InitializeContext (System.String url,
+System.Xml.XmlParserContext context, System.IO.TextReader fragment,
+XmlNodeType fragType)
+in <0x0009c> System.Xml.XmlTextReader:.ctor (System.String url,
+System.IO.TextReader fragment, XmlNodeType fragType,
+System.Xml.XmlParserContext context)
+in <0x00065> System.Xml.XmlTextReader:.ctor (System.String xmlFragment,
+XmlNodeType fragType, System.Xml.XmlParserContext context)
+in [0x00009] (at /home/hcs/Test.cs:10) Test:Main (System.String[] args)
+
+Expected Results:
+XmlDeclaration
+
+How often does this happen? 
+Always.
+
+Additional Information:
+Tested with 1.1.9 20050927.
+Problem seems to be in System.Xml.XmlTextReader:SkipTextDeclaration()
+Hopefully not a duplicate this time ;-)
