The following automatic conversions were performed:

'_symmetry_cell_setting' value 'Cubic' changed to 'cubic' according
to the built-in table from CIF Core dictionary named 'cif_core.dic'
version 2.4.1 from 2010-06-29.

'_exptl_crystal_density_meas' value 'not measured' was changed to '?'
- the value is perceived as not measured.
