Definition:
Mass percentage of the chemical species given in
_atom_analytical.chemical_species as derived from elemental analysis.
This is most often used in elemental compositions determined by
X-ray fluorescence, where elements are reported as equivalent mass
percentages of their relevant oxide. For example: Al is reported
as Al2O3, P is reported as P2O5.
