+Summary: XmlDocument incorrectly performs Xml Name validation 
+Description of Problem:
+The mono implementation of XmlDocument performs element name validation.
+The Microsoft implementation of XmlDocument does not. I would speculate
+that Microsoft rely on the XmlReader implementations to perform this
+The problem with mono not conforming to this approach is that an XmlReader
+which returns invalid names (for example a gconf reader or windows registry
+reader) will work fine with Microsoft's implementation, but work
+incorrectly in Mono.
+An real-world example of a popular XmlReader which returns invalid names is
+Steps to reproduce the problem:
+1. Return an invalid name from an XmlReader implementation
+2. Load that XmlReader into XmlDocument
+3. Run the resulting assembly in mono and Microsoft's .Net
+Actual Results:
+Unhandled Exception: System.Xml.XmlException: '!INVALIDNAME' is not a valid
+XML Name
+  at System.Xml.XmlConvert.VerifyName (System.String name) [0x00000] 
+  at System.Xml.XmlElement..ctor (System.String prefix, System.String
+localName, System.String namespaceURI, System.Xml.XmlDocument doc, Boolean
+atomizedNames) [0x00000] 
+  at System.Xml.XmlDocument.CreateElement (System.String prefix,
+System.String localName, System.String namespaceURI) [0x00000]

+  at System.Xml.XmlDocument.Load (System.Xml.XmlReader xmlReader) [0x00000] 
+  at TestCase.Main () [0x00000] 
+Expected Results:
+No errors
+How often does this happen?
