Changes

*DeleteRecordingSchedules is '''intended for deleting individual ("child") recordings, existing in the user's STB''', but not cancelling or deleting the whole definition (RecordingDefinition). * Clients must invoke DeleteRecordingSchedule sending the id of the Recording (not RecordingDefinition in the case of Mediaroom) to delete within the recordingScheduleId. If several recordings must be deleted, client will have to request it through sequential requests (one by one)* Since the behavior of DeleteRecordingSchedule in Mediaroom is "to remove the completed recordings on the STB", it does not make sense to request the deletion of a whole series, so '''method will return an error if it is invoked requesting an entireSeries deletion in Mediaroom'''.
