Programming in Apache Qpid (or any other doc / wiki I search) has no word about particular parameters we can specify in x-declare map in address string. Only a note that "values correspond to the valid fields on an AMQP 0-10 queue-declare or exchange-declare command. ".
I think it is worth to put those params to Programming in Apache Qpid also, as a developer is not required to read AMQP specification to understand that these params are available:
auto-delete: boolean specifies auto-delete-ness of the queue/exchange
exclusive: boolean specifying exclusiveness of the queue/exchange
alternate-exchange: alternate exchange where messages shall be routed to when this queue is deleted / the exchange fails to find a matching bind for a message
arguments: a nested map with arguments available specifically for the queue / exchange (link to https://cwiki.apache.org/confluence/display/qpid/Qpid+extensions+to+AMQP is worth to provide)
A table similar to "Table 2.3. Link Properties" would be great to be created.
