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 '>523' was changed to
'523' - it should be numeric and without a unit designator.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc w =
1/[\s^2^(Fo^2^)+(0.0322P)^2^] where P = (Fo^2^+2Fc^2^)/3' was changed
to 'calc'. New tag '_refine_ls_weighting_details' was created. The
value of the new tag was set to 'w = 1/[\s^2^(Fo^2^)+(0.0322P)^2^]
where P = (Fo^2^+2Fc^2^)/3'.
