// An application can be notified when its configuration properties are modified

// PropertiesAdminUpdateCallback and register it with the facet. The facet
// implements the class NativePropertiesAdmin, so the application needs to
// downcast the facet to this type in order to register the callback.
//
// For example:
//
// Ice::ObjectPtr obj = communicator->findAdminFacet("Properties");
// assert(obj); // May be null if the facet is not enabled
// NativePropertiesAdminPtr facet = NativePropertiesAdminPtr::dynamicCast(obj);
// PropertiesAdminUpdateCallbackPtr myCallback = ...;
// facet->addUpdateCallback(myCallback);
//
// Ice ignores any exceptions raised by the callback.
