-		Version 1.3
-
-		The primary goals of this format is to allow a simple XML format 
-		that is mostly human readable. The generation and parsing of the 
-		various data types are done through the TypeConverter classes 
-		associated with the data types.
-
-		Example:
-
-		... ado.net/XML headers & schema ...
-		<resheader name="resmimetype">text/microsoft-resx</resheader>
-		<resheader name="version">1.3</resheader>
-		<resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
-		<resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
-		<data name="Name1">this is my long string</data>
-		<data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
-		<data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
-			[base64 mime encoded serialized .NET Framework object]
-		</data>
-		<data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
-			[base64 mime encoded string representing a byte array form of the .NET Framework object]
-		</data>
-
-		There are any number of "resheader" rows that contain simple 
-		name/value pairs.
-
-		Each data row contains a name, and value. The row also contains a 
-		type or mimetype. Type corresponds to a .NET class that support 
-		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.
-
-		mimetype: application/x-microsoft.net.object.binary.base64
-		value   : The object must be serialized with 
-			: System.Serialization.Formatters.Binary.BinaryFormatter
-			: and then encoded with base64 encoding.
-
-		mimetype: application/x-microsoft.net.object.soap.base64
-		value   : The object must be serialized with 
-			: System.Runtime.Serialization.Formatters.Soap.SoapFormatter
-			: and then encoded with base64 encoding.
-
-		mimetype: application/x-microsoft.net.object.bytearray.base64
-		value   : The object must be serialized into a byte array 
-			: using a System.ComponentModel.TypeConverter
-			: and then encoded with base64 encoding.
