known property

bool? known

Known is false when this plane held nothing knowable at AsOf. That is an answer, not an error.

Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.

Implementation

bool? known;
