Query a specific agent registered with this zone (a directed query) and notify a MessagingListener. Directed queries are used primarily when the source of data is known because of a message previously received from that agent. For example, if your agent receives a SIF_Event and you wish to query the author of that event for additional data, a directed query is appropriate. In addition, some kinds of SIF Data Objects in SIF 1.5 and later may be designed to require agents to send directed queries if more than one agent in a zone typically offers support for the object. This is necessary because only one agent can be the authoritative provider of a given object type in each zone.
