Annotations
A clothoid, or Cornu's spiral, is plane curve whose curvature is a fixed function of its length.
refLocation, startParameter, endParameter and scaleFactor have the same meaning as specified in ISO 19107:2003, 6.4.22.
interpolation is fixed as "clothoid".
The content model follows the general pattern for the encoding of curve segments.
