+Summary: Cannot write out simple XML file using XPathNavigator
+
+My apologies if I'm missing something basic, but after a couple hours of web searching, I am 
+unable to see what's wrong with this example.  I have the following data in "file.xml":
+
+<?xml version="1.0"?>
+<one>
+	<two>Some data.</two>
+</one>
+
+And I have this test program:
+
+using System;
+using System.Xml;
+using System.Xml.XPath;
+
+namespace Test
+{
+	public class MyTest
+	{
+		public static int Main(string[] args)
+		{
+			XPathDocument doc = new XPathDocument(args[0]);
+			XPathNavigator nav = doc.CreateNavigator();
+			//nav.MoveToRoot();    // this makes no difference
+			Console.Write(nav.OuterXml);
+			return 0;
+		}
+	}
+}
+
+According to what I've read, this should output the XML data.  And if there is no embedded 
+<two> tag, this is just what it does.  But once I have any nested tags, it gives me an exception:
+
+~ $ mono --debug test.exe file.xml
+
+Unhandled Exception: System.InvalidOperationException: There was no XML start tag open.

+
+I've combed through XmlWriter.cs and friends, but nothing jumps out at me.  Either I'm doing 
+something very wrong, or there's indeed a reason to trouble your inbox.  Btw, I derived this code 
+from examples in the .NET documentation.
