+
+using System;
+using System.Xml;
+using System.Xml.Serialization;
+
+public class Test
+{
+        public static void Main ()
+        {
+                Test t = new Test ();
+                t.Namespaces.Add ("", "urn:foo");
+                XmlSerializer ser = new XmlSerializer (typeof (Test));
+                ser.Serialize (Console.Out, t);
+        }

+        public XmlSerializerNamespaces Namespaces = new XmlSerializerNamespaces

+
+$ ./xs
+<?xml version="1.0" encoding="shift_jis"?>
+<Test xmlns:xsd="http://www.w3.org/2001/XMLSchema"
+xmlns:xsi="http://www.w3.org/

+<Test xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+xmlns:xsd="http://ww
+w.w3.org/2001/XMLSchema" xmlns:="urn:foo" />
+How often does this happen?
