checkCIF procedure

PLAT762

 The CIF contains no X-Y-H or H-Y-H bond angles. This might be caused by not
 using the SHELXL instruction BOND $H. Those data should also be supplied   
 when H-atoms are introduced on calculated positions and/or refined riding on
 their carrier atom. Inclusion is required by Acta Cryst. but not necessarily
 so by other journals.
