A MultiTopicProducer sends messages to a destination with zero or more subtopics. It is like the regular Producer but it can direct the message to any consumer who is subscribing to any one of a number of subtopics. If the consumer is a MultiTopicConsumer and that consumer has subscribed to more than on subtopic in the list of subtopics used by the producer, the consumer only receives the message once.

The MultiTopicProducer will dispatch a MessageAckEvent or MessageFaultEvent for each message they send depending upon whether the outbound message was sent and processed successfully or not.
