A purpose held by an Actor that is declared to be of 'Strategic' importance.
A Strategic-Purpose may Help-Achieve another Purpose, and thus be lower-level with respect to that Purpose. However, any such Purpose that is higher-level than at least one Strategic-Purpose must itself be a Strategic-Purpose.
