Together with 'GI.Atk.Objects.Plug.Plug', 'GI.Atk.Objects.Socket.Socket' provides the ability to embed
accessibles from one process into another in a fashion that is
transparent to assistive technologies. 'GI.Atk.Objects.Socket.Socket' works as the
container of 'GI.Atk.Objects.Plug.Plug', embedding it using the method
'GI.Atk.Objects.Socket.socketEmbed'. Any accessible contained in the 'GI.Atk.Objects.Plug.Plug' will
appear to the assistive technologies as being inside the
application that created the 'GI.Atk.Objects.Socket.Socket'.

The communication between a 'GI.Atk.Objects.Socket.Socket' and a 'GI.Atk.Objects.Plug.Plug' 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 'GI.Atk.Objects.Plug.plugGetId' and 'GI.Atk.Objects.Socket.socketEmbed', so an ATK
implementor shouldn\'t reimplement them. The process that contains
the 'GI.Atk.Objects.Plug.Plug' is responsible to send the ID returned by
@/atk_plug_id()/@ to the process that contains the 'GI.Atk.Objects.Socket.Socket', so it
could call the method 'GI.Atk.Objects.Socket.socketEmbed' in order to embed it.

For the same reasons, an implementor doesn\'t need to implement
'GI.Atk.Objects.Object.objectGetNAccessibleChildren' and
'GI.Atk.Objects.Object.objectRefAccessibleChild'. All the logic related to those
functions will be implemented by the IPC layer.
