Airspace2 is used as aggregation component (parent) with operation equal-to 'SUBTR', operationSequence equal-to '2'
Subsequently, the geometry of Airspace3 is the result of the aggregation of the two components.

This method might be appropriate for applications that need to provide fully digested geometrical data for direct consumption (e.g. graphical visualization, spatial calculations). The disadvantage of this method is that the referenced geometry might also change in time. This is not a problem when the aggregation is used for the provision of SNAPSHOT data (valid at a time instant), but it might become problematic when providing BASELINE data (which is valid for a period of time). Future changes of the geometry of referenced airspace needs to be propagated to the AirspaceVolume of the aggregated airspace. The advantage is that this method provides complete geometrical data for the aggregated Airspace and does not require further calculations by the client system.

The dependency attribute will be used to define, if only the horizontal limits of the "parent" airspace(s) shall be taken into account considered or also the vertical limits (i.e. the full geometry).
