The action-responder Topic has the form:

<Prefix>/<Encoding>/action-responder/<Responder>

The <Responder> Topic level is the PublisherId for the Responder of the Actions. This value shall be the same as the PublisherId in PubSubConnection provided in the message.

The PublisherId in the PubSubConnection uniquely identifies the Publisher within the scope defined by the <Prefix>. If it is a String, it should be as short as possible since long Topic names degrade performance.

The messages are instances of the PubSubConnection MessageType (see 7.2.2).
