32 * @brief The minimalistic, always empty Accessible object with settable address.
34 * To be used as a proxy object, in those situations where you want to return an address in
35 * a different bridge (embedding for example), but the object itself isn't planned to be used
36 * otherwise. This object has a settable parent, no children, an empty name and so on.
