    <xs:documentation>The Cylinder23Type defines the geometric entity 'cylindrical_surface(u,v):R2->R3'. Any surface can have an additional transformation matrix. The cylinder is bounded below by a plane passing through the AxisPoint of the axis and normal to the axis. The cylinder is bound above by a plane that (1) passes through a point on the axis a distance Length along the axis from the axis point in the direction of the axis and (2) is normal to the axis.</xs:documentation>
