Interface AirspaceByIdentifierOptions

When true (the default), ARTCC features for the identifier are included alongside the airport-associated and SUA features. When false, ARTCC features are excluded - useful when you only want the non-ARTCC partition for an identifier without enumerating every non-ARTCC type yourself.

Ignored when types is provided: types is the authoritative inclusion list in that case.

Optional set of airspace types to include in the results. When provided, acts as an inclusion filter and overrides the partition between ARTCC and non-ARTCC features: callers who want ARTCC results in addition to the usual partition include 'ARTCC' in this set explicitly, and callers who want only non-ARTCC results pass a set of the non-ARTCC types. When omitted, every type is eligible (subject to includeArtcc).
