etaXsiRelHeightPointType

A point above or below the chord surface of the component segment, the surface spanned by the chord lines of its elements (see componentSegmentType): it lies on the normal of the chord surface through the point with the relative coordinates η (eta) and ξ (xsi).

relHeight gives its position on that normal, relative to the thickness of the wing at this place: 0 is the point on the lower and 1 the point on the upper surface of the wing, and values in between are interpolated linearly. Without relHeight the point lies on the chord surface.

The referenceUID selects the coordinates: it references either a segment of the wing, and the values are then the coordinates of that segment (wingSegmentType), or a component segment, and the values are then the coordinates of the component segment (componentSegmentType).
