* xml_producer.cpp
*
* This is one of three programs used to implement XML-based content
* routing in C++.
*
* declare_queues.cpp
*
* Creates a queue named "message_qaueue" on the broker,
* declares an XML Exchange, subscribes the queue to the XML
* Exchange using an XQuery in the binding, then exits.
*
* xml_producer.cpp (this program)
*
* Publishes messages to the XML Exchange.
*
* listener.cpp
*
* Reads messages from the "message_queue" queue.
