+         A diffraction pattern containing three phases (PHASE_A, PHASE_B, and
+         PHASE_C) has been quantified using the I/Ic specialisation of the RIR
+         algorithm.
+
+         The I/Ic value for each of the phases is specified by the values of
+         _pd_qpa_calib_factor.I_over_Ic. The intensity factors to which each
+         of the I/Ic values are applied are given by the values of
+         _pd_qpa_intensity_factor.value.
+
+         The quantification values given by _pd_phase_mass.percent can now be
+         confirmed by following the I/Ic algorithm detailed in
+         _pd_qpa_overall.method.
+
+         As there are loops containing data names linked to key data names of
+         Set categories (_pd_phase_mass.phase_id and
+         _pd_qpa_intensity_factor.phase_id), the _audit.schema value for the
