+
+        This is the entry point for an application that wants to register itself against
+        the accessibility registry.  The application's root object, which it passes in
+        @plug, must support the org.a11y.atspi.Application interface.
+
+        When an application calls this method on the registry, the following handshake happens:
+
+        * Application calls this method on the registry to identify itself.
+
+        * The registry sets the "Id" property on the org.a11y.atspi.Application interface on the @plug 
object.
+
+        * The Embed method returns with the bus name and object path for the registry's root object.
+
+        Returns: the bus name and object path of the registry's root object.
