The MIME Application/Vnd.pwg-multiplexed Content-Type
Robert G. Herriot · 2002
The IESG believes use of this media type is only appropriate in situations where the producer is fully aware of the capabilities and limitations of the consumer.In particular, this mechanism is very dependent on the producer knowing when the consumer will need a particular component of a multipart object.But consumers potentially work in many different ways and different consumers may need different things at different times.This mechanism provides no means for a producer to determine the needs of a particular consumer and how they are to be accommodated.Alternative mechanisms, such as a protocol based on BEEP which is capable of bidirectional communication between the producer and consumer, should be considered when the capabilities of the consumer are not known by the producer.
