The following automatic conversions were performed:

data item '_symmetry_cell_setting' value 'Monoclinic' was changed to
'monoclinic' in accordance with the built-in table derived from the
CIF Core dictionary named 'cif_core.dic' version 2.4.5 last updated
on 2014-11-21.

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