This includes generic OLE shapes, frames, plugins, and applets.
This service supports the additional ::drafts::com::sun::star::accessibility::XAccessibleAction
interface.
OLE objects are handled as place holders. While not activated the
accessible OLE shape is the only indicator of the OLE objects'
existence. When an OLE object has been activated then the accessbility
tree representing it (as far as that is available) is included directly
under the accessible document view and not under the OLE object. This
is due to underlying implementation constraints and may change in the
future.
