+	<!-- 
+		Microsoft ResX Schema
+
+		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.
