  <!-- 

    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.
