The following automatic conversions were performed:

data item '_chemical_melting_point' value '393K' was changed to '393'
-- the value should be numeric and without a unit designator.

data item '_exptl_crystal_density_meas' value 'none' was changed to
'?' -- the value is perceived as not measured.
