/** \details
  The IfcBSplineSurface is a general form of rational or polynomial parametric surface.
  The descriptions of symbols used below:
  <table>
  <b>Variable</b>                     <b>Definition</b>
  K1                                  Upper index on U control points
  K2                                  Upper index on V control points
  P<sub>ij</sub>                      Control points
  w<sub>ij</sub>                      Weights
  d1                                  U degree
  d2                                  V degree
  </table>
  
  The control points are ordered as: P<sub>00</sub>, P<sub>01</sub>, P<sub>02</sub>, ..., P<sub>K1(K2-1)</sub>, P<sub>K1K2</sub>
  
  The weights, in the case of the rational subtype, are ordered similarly.
  
  For each parameter, s = u or v, if k is the upper index on the control points and d is the degree for s, 
  the knot array is an array of (k + d + 2) real numbers [s<sub>-d</sub>, ...., s<sub>k+1</sub>], 
  such that for all indices j in [-d, k]; s<sub>j</sub> ≤ s<sub>j+1</sub>. 
  This array is obtained from the appropriate u_knots or v_knots list by repeating each multiple knot according to the multiplicity.

  This definition may not be instantiated.
