+Summary: Creating an 'xmlns' attribute results in duplicate attribute
+
+Creating an xmlns attribute results in a duplicate attribute being generated.
+
+The following code will result in two 'xmlns' attributes in the generated xml :
+
+XmlDocument doc = new XmlDocument();
+doc.AppendChild(doc.CreateElement("root"));
+                                                                          
+     
+// create 'xmlns' attribute and add it to document
+XmlAttribute attr = doc.CreateAttribute("xmlns");
+attr.Value = "http://none";
+doc.DocumentElement.Attributes.Append(attr);
+                                                                          
+     
+// save xml document
+doc.Save("builddoc.xml");
+
+(full test case is provided as attachment)
+
+this will generate the following invalid xml fragment :
+
+<root xmlns="http://none" xmlns="" />
