OARIS — Semantics of sector_added unclear for use case manage_transmission_sectors

The attribute sector_added :Boolean in class transmission_sector_type has no descriptive text. The semantics of this attribute are not readily deduced, nor can a coherent proposal for what they should be for all instances of the class be formed. For instance, it should be noted that the class is used both for the CMS to request a setting and for the Sensor to report its current state. Equally, there are not attributes to indicate that a sector has been or should be removed.

Remove attribute sector_added

Attribute sector_added from class transmission_sector_type should be removed as it is both ill-defined and also unnecessary. Both the CMS and a Sensor are able to deduce which sectors have been added, updated or removed (if necessary for their processing) as each sector has its own unique sector_id. Also, having an attribute sector_added etc. makes it possible for the data to be inconsistent - not a good feature.
