+Summary: NullReferenceException in DTDValidatingReader.FilterNormalization
+
+NullReferenceException in DTDValidatingReader.FilterNormalization
+
+Using 'XmlReader' with ValidationType.DTD and a XmlResolver to provide 
+access to the DTD file.  The XML document contains an element with an 
+undefined attribute.  When run on MSFT v2.0.50727 CLR, this fails 
+(correctly) with:
+  System.Xml.Schema.XmlSchemaException  "The 'xxxsize' attribute is not 
+declared."
+
+However with Mono 1.2.2.1 (mono-1.2.2.1-gtksharp-2.8.3-win32-0.exe) it 
+always fails with the following:
+ Unhandled Exception: System.NullReferenceException: Object reference not 
+set to an instance of an object

+attrName, System.String rawValue) [0x00000]

+I will attach a small C# program that reproduces this.  Simply run it on 
+the console.  It simply xmlRdr.Read()'s its way through an example XML 
+document that produces this fault.  It includes a simply hacky 
+XmlResolver implementation to provide access to the DTD which is included 
+in the source as a string.
