+    <title>SERVICE DISCOVERY</title>
+    <para>
+        The service discovery feature allows back ends to automatically find the
+appropriate servers to connect to using a special DNS query. This feature is
+not supported for backup servers.

+        <para>
+            If no servers are specified, the back end automatically uses service
+discovery to try to find a server. Optionally, the user may choose to use
+both fixed server addresses and service discovery by inserting a special
+keyword, <quote>_srv_</quote>, in the list of servers. The order of
+preference is maintained. This feature is useful if, for example, the user
+prefers to use service discovery whenever possible, and fall back to a
+specific server when no servers can be discovered using DNS.
