x-declare block?  They both refer to values used in queueDeclare, but it seems like they are
not equivalent.

The 'node' is the primary broker entity of interest, usually the 
rendezvous point between senders and receivers. The 'link' is the 
association between senders/receivers and that node.

In the case of a 'topic' the node is an exchange and the receivers link 
involves a subscription queue that is bound to that exchange and a 
subscription to that queue.

Therefore in this case the x-declare in the node block will control the 
declaration of the exchange (if necessary), while that in the link block 
will control the subscription queue that is bound to the exchange.
