+    
+    The primary goals of this format is to allow a simple XML format

+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:

+                
+    There are any number of "resheader" rows that contain simple

+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+
