+Summary: [2.0] Tagmapping does not check if type derives from original type
+
+Currently, we do not check whether the type specified in the mappedTagType 
+attribute derives from the original type (specified in the tabType 
+attribute).
+
+MS throws the following exception if not:
+
+[ConfigurationErrorsException]: The specified type 'Mono.Web.UI.TextBox' 
+used for mapping must inherit from the original 
+type 'System.Web.UI.WebControls.TextBox'. (...webbug...\web\web.config
