+Summary: DataSet with Column of MappingType = Attribute does not deserialize properly
+
+Please fill in this template when reporting a bug, unless you know what 
+you are doing.
+Description of Problem:
+
+Paste the following code into a simple console app to recreate the error:
+
+string filePath = @"/usr/people/dclough/mono/exe/serialized.xml";
+
+DataSet quota = new DataSet("Quota");
+
+// Dimension
+quota.Tables.Add("Dimension");
+
+quota.Tables["Dimension"].Columns.Add("Number", typeof(int));
+quota.Tables["Dimension"].Columns["Number"].AllowDBNull = false;
+quota.Tables["Dimension"].Columns["Number"].ColumnMapping = 
+MappingType.Attribute;
+
+quota.Tables["Dimension"].Columns.Add("Title", typeof(string));
+quota.Tables["Dimension"].Columns["Title"].AllowDBNull = false;
+quota.Tables["Dimension"].Columns["Title"].ColumnMapping = 
+MappingType.Attribute;
+
+quota.Tables["Dimension"].Rows.Add(new object[] { 0, "Hospitals" });
+quota.Tables["Dimension"].Rows.Add(new object[] { 1, "Doctors" });
+
+quota.Tables["Dimension"].Constraints.Add("PK_Dimension", quota.Tables
+["Dimension"].Columns["Number"], true);
+
+quota.AcceptChanges();
+
+XmlSerializer ser = new XmlSerializer(quota.GetType());
+FileStream f = File.Create(filePath);
+
+try
+{
+        ser.Serialize(f, quota);
+        f.Close();
+
+	f = File.Open(filePath, FileMode.Open, FileAccess.Read, 
+FileShare.Read);
+	object obj = ser.Deserialize(f);
+}
+catch (Exception ex)
+{
+	System.Console.WriteLine(ex);
+} 
+
+Actual Results:
+
+The above code throws an exception upon deserialization.
+
+Expected Results:
+
+The serialized data in the file should be deserialized with a DataSet 
+created.
+
+How often does this happen?
+
+Repeatable with the above code.
+
+
+Additional Information:
+
+I believe the code to be altered is in the LoadColumns method of the 
+XmlDiffLoader class.
