Will try to understand this, but until that a new question has arisen in 
my mind:
from the STOMP page it seems amq.topic has a special meaning in STOMP, 
the name is what triggers this function:
"For SUBSCRIBE frames, a shared queue is created for each distinct 
subscription ID x destination pair, and bound to the amq.topic exchange 
with routing key <name>. A subscription is created against the queue."

Wouldn't be possible to extend this to take the exchange's type into 
account as well?

I mean, would it work to create a new topic exchange and when I durably 
subscribe to /exchange/myownexchange.routing.key from STOMP, it would be 
treated the same as I would subscribe to a topic durably if that 
exchange is of topic type?
