+ * SECTION:atksocket
+ * @Short_description: Container for AtkPlug objects from other processes
+ * @Title: AtkSocket
+ * @See_also: #AtkPlug
+ *
+ * Together with #AtkPlug, #AtkSocket provides the ability to embed
+ * accessibles from one process into another in a fashion that is
+ * transparent to assistive technologies. #AtkSocket works as the
+ * container of #AtkPlug, embedding it using the method
+ * atk_socket_embed(). Any accessible contained in the #AtkPlug will
+ * appear to the assistive technologies as being inside the
+ * application that created the #AtkSocket.
+ *
+ * The communication between a #AtkSocket and a #AtkPlug is done by
+ * the IPC layer of the accessibility framework, normally implemented
+ * by the D-Bus based implementation of AT-SPI (at-spi2). If that is
+ * the case, at-spi-atk2 is the responsible to implement the abstract
+ * methods atk_plug_get_id() and atk_socket_embed(), so an ATK
+ * implementor shouldn't reimplement them. The process that contains
+ * the #AtkPlug is responsible to send the ID returned by
+ * atk_plug_id() to the process that contains the #AtkSocket, so it
+ * could call the method atk_socket_embed() in order to embed it.
+ *
+ * For the same reasons, an implementor doesn't need to implement
+ * atk_object_get_n_accessible_children() and
+ * atk_object_ref_accessible_child(). All the logic related to those
+ * functions will be implemented by the IPC layer.
