   The code identifying the class to which this reflection has
   been assigned. This code must match a value of
   _diffrn_reflns_class_code. Reflections may be grouped into
   classes for a variety of purposes. For example, for modulated
   structures each reflection class may be defined by the
   number m=sum|m~i~|, where the m~i~ are the integer coefficients
   that, in addition to h,k,l, index the corresponding diffraction
   vector in the basis defined for the reciprocal lattice.
