If multiple changes happen at the same time (or in a time interval sufficiently small for a service to recognize them as belonging together) then they constitute one capabilities changed event. A new offering - as defined by the SWE Service Model - was added to the service. An offering- as defined by the SWE Service Model - was deleted from the service. The description of a sensor was updated, meaning that information contained in the current and / or previous versions of the sensor's description was added, removed or modified. A sensor was inserted at the service, resulting in a new offering - as defined by the SWE Service Model - having been added to the service.
