Set of possible nominal property values for nominal properties of a given kind-of-nominal-property.
Examples:
- {milky, red, yellow} can be a nominal property value set for nominal properties with the kind-of-nominal-property "colour".
- {A, B, AB, O} can be a nominal property value set of four nominal property values for nominal properties with the kind-of-nominal-property "blood group".
- Nominal property value sets that are ordered by other means than size, e.g. numbering of chromosomes and alphabetical list of country codes.
Note: A "nominal property value set" can be ordered by convention, for example in alphabetic order of words, or alphanumerical codes identifying nominal property values, or an order reflecting a classification, but neither of these is an ordering by size.
