Create a non-durable queue with random name and exclusivity policy “link”. Bind queue to exchange “exchange” using binding key “binding”. Broker replies with attach having capability “topic” on a source and attach offered capability “SHARED_SUB”.

Create a durable queue with name derived from link name, container id and source durability. Exclusivity policy is set to “link”. Bind queue to exchange. Broker replies with attach having capability “topic” on a source and attach offered capability “SHARED_SUB”.

If queue already exists the link should be refused with error “resource locked”

Create a durable queue with name derived from link name, global name space and source durability. Exclusivity policy is set to “link”. Bind queue to exchange. Broker replies with attach having capabilities “topic” and “global” on a source and attach offered capability “SHARED_SUB”.

Create a non-durable queue with name derived from link name (up to “|”), container id and source durability. Exclusivity policy is set to “shared”. Bind queue to exchange. Broker replies with attach having capabilities “topic” and “shared” on a source and attach offered capability “SHARED_SUB”.

If queue already exists and filters and/or binding key are not the same as derived from attach source, then:

• if there is/are existing consumer(s), refuse the link with error “resource locked”

• if there is no consumer, rebind queue using new filters and/or binding key

If existing queue exclusivity policy is not “shared”, then link creation is refused with error “resource locked”.

If existing queue lifetime and/or durability are different from expected, then link creation is allowed but the source fields in the reply should be modified accordingly.
