Optional parameters: No optional parameters Encoding considerations: Each message of an Application/Vnd.pwg-multiplexed entity can be encoded in any manner allowed by the Content- Type of the message. However, using the reasoning of Multipart, the Application/Vnd.pwg-multiplexed entity cannot be encoded. Otherwise, a message would be encoded twice, once at the message level and once at the Application/Vnd.pwg-multiplexed level. Security considerations: See section 6 (Security Considerations) of RFC 3391. Published specification: RFC 3391.
