+    <p>The Registry is a service through which applications providing 
+      accessibility services (servers) can rendezvous with consumers of those
+      services (Assistive Technologies).  The Registry is the first &quot;port of call&quot; for 
+      accessible applications and for assistive technologies wishing to query and
+      interact with those applications.  </p>
+
+    <p>The Registry service provides four basic functions to Assistive Technology (AT) clients:
+      \li it provides a list of the applications who have registered with the AT-SPI
+      framework, thereby announcing their participation in the AT-SPI framework;
+      \li it allows AT clients to register for notification of changes in application
+      state (at-spi Events);
+      \li it dispatches/relays said events from participating applications to
+      the registered listeners;
+      \li it gives access to system device events via the associated DeviceEventController
+      interface.  </p>
+
+    <p>From the point of view of accessible applications (i.e. AT-SPI service producers), 
+      the Registry is primarily a registration and event delivery service.  Applications 
+      normally only call the registerApplication and deregisterApplication Registry methods,
+      and its inherited EventListener::notifyEvent method.  </p>
+
+    <p>@note Although all application events are dispatched via the Registry, other AT client 
+      calls are serviced directly by the applications, rather than being relayed via the
+      Registry.  The AT client obtains references to these application objects
+      via the enumeration of Desktop instances whose children are Application instances
+      (Registry::getDesktopList) and via examination of the 'source' member of the Event 
+      structure.   </p>
+
+    <p>The Registry normally lives in its own process space; communication via Registry and
+      both application services and AT clients takes place via IPC.  A process space diagram
+      illustrating the relationship between applications, Registry, and AT is shown below.
