As far as I understand, rabbit-stomp gateway implements
a subset of AMQP features - but over a STOMP protocol.

For example a STOMP 'destination' is treated as an AMQP 'queue',
but this abstractions represent slightly different thing.

As Matthias pointed out, STOMP spec doesn't give much information
of what the defaults should be. The problem is that even if changing
the defaults is easy, we must take care of all the other use cases.

Right now the default behavior is sane from the AMQP
point of view. Later you can get any kind of behavior you want
by playing with the extra parameters.
