Transaction Context Support
A Broker client initiates a transaction to publish, acknowledge, or get the events that make up the transaction, then ends the transaction by committing or aborting the events. Other features of transaction context support are:
*After an ABORT operation, all request events in the transaction are discarded and will not generate reply any events, not even error replies.
*All operations throw exceptions.
*Any request event that generates an error following a COMMIT operation will cause subsequent events to be discarded. Furthermore, any changes from prior events will be rolled back. If an error occurs, an exception (either AWPR_ERROR_UNKNOWN_TRANSACTION, AWPR_ERROR_INVALID_TRANSACTION, or AWPR_ERROR_INVALID_CLIENT) will be thrown.
