This token indicates the relationship between the parameterisation and 3-space
extent.  It takes one of the following values:

    PK_PARAM_form_linear_c       parameter is proportional to distance along
                                 a straight line.  For a surface the straight
                                 line corresponds to a constant value of the
                                 other parameter
    PK_PARAM_form_circular_c     parameter represents an angle round a circle
                                 For a surface, the circle corresponds to a
                                 constant value of the other parameter.
    PK_PARAM_form_mesh_c         surface is a mesh. See here for
                                 more information on mesh parameterisation.
    PK_PARAM_form_any_c          not one of the above
