PLAT609

 The presence of an ABIN instruction in the SHELXL .ins file implies the use 
 of the PLATON/SQUEEZE or OLEX2/MASK tool to take into account the disordered
 solvent contribution to the calculated structure factors. The corresponding
 procedure details, generated by those programs, appear to be absent from or
 incorrectly modified as part of the CIF embedded '.fab' file.
