class TranslateCompositeCurve from StepToTopoDS 
    inherits Root from StepToTopoDS
	---Purpose: Translate STEP entity composite_curve to TopoDS_Wire
	--          If surface is given, the curve is assumed to lie on that
        --          surface and in case if any segment of it is a
	--          curve_on_surface, the pcurve for that segment will be taken.
	--          Note: a segment of composite_curve may be itself 
        --                composite_curve. Only one-level protection against 
        --                cyclic references is implemented.
