        <documentation>This variant of the arc requires that the points on the arc have to be computed instead of storing the coordinates directly. The control point is the center point of the arc plus the radius and the bearing at start and end. This represenation can be used only in 2D.</documentation>

GML supports two different ways to specify the control points of a curve segment.
1. A "pos" (DirectPositionType) or "pointProperty" (PointPropertyType) element. The "pos" element contains a center point that is only part of this curve segment, a "pointProperty" element contains a point that may be referenced from other geometry elements or reference another point defined outside of this curve segment (reuse of existing points).
2. The "posList" element can be used to specifiy the coordinates of the center point, too. The number of direct positions in the list must be one.

The attribute "interpolation" specifies the curve interpolation mechanism used for this segment. This mechanism
uses the control points and control parameters to determine the position of this curve segment. For an ArcByCenterPoint the interpolation is fixed as "circularArcCenterPointWithRadius".
