-Microsoft ResX Schema
-Version 2.0
-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">2.0</resheader>
-<resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
-<resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
-<data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
-<data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
-<data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
-<value>[base64 mime encoded serialized .NET Framework object]</value>
-</data>
-<data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
-<value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
-<comment>This is a comment</comment>
-</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.Runtime.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.
