# Categorical value specification: a characteristic whose value is a category, not a number. The ferrite of specimen
# A-13 has the crystal structure "body-centred cubic"; a ladle melt has the aggregate state "liquid". Each category is a
# categorical value specification that specifies the value of the quality. Invented specimen, heat and values.
