The following automatic conversions were performed:

data name '_chemical_melting_point' was changed to
'_chemical_temperature_decomposition_gt' since the value was
specified as 'more than' ('>') a certain temperature. The value
'>453K dec.' was changed to '453' -- it should be numeric and without
a unit designator.
