The following automatic conversions were performed:

'_chemical_melting_point' tag was changed to
'_chemical_melting_point_gt' since the value was specified 'more
than' ('>') a certain temperature. The value '>443' was changed to
'443' - it should be numeric and without a unit
designator.

'_exptl_absorpt_correction_type' value 'Multi-scan'
changed to 'multi-scan' according to the built-in table from CIF Core
dictionary named 'cif_core.dic' version 2.4.1 from 2010-06-29.
