style='font-size:12.0pt;color:windowtext'>1. I have a basic question about
transactions in AMQP. What exactly does a transaction include/mean? For example,
does it include the administrative features like creation of queues, exchanges,
etc that will be auto-deleted if the client aborts the transaction. I’m
not entirely clear about this, so I’m just trying to understand and figure
out possibilities. The spec says that messages and acknowledgments are covered
in a transaction. What would happen if the publisher sends a message to the
broker/queue, consumer receives (reads it from the queue) and processes it, sends
an ack to the broker and then the publisher decides to abort the transaction?
How can this transaction be atomic and/or rolled-back since the message is
already gone? <o:p></o:p></span></font></p>

a reliable transport layer (TCP, SCTP, etc) and no unreliable connection (say,
UDP)? If yes, will the later releases work on including unreliable transport
layer protocols?<o:p></o:p></span></font></p>
