To get access to the record definitions for the structures use:
-include_lib("cosNotification/include/*.hrl").
All objects, which inherit this interface, export functions described in this module.
Object = #objrefReply = [QoSProperty]QoSProperty = #'CosNotification_Property'{name, value}name = string()value = #anyThis operation returns list name-value pairs which encapsulates the current QoS settings for the target object.

If it is not possible to set the requested QoS the UnsupportedQoS
exception is raised, which inlcudes a sequence of PropertyError's
describing which QoS, possible range and why is not allowed.
