The following describes each feature and its values and defines the terms. While the features are independent of each other, individual values can certainly relate to other values. For example, the value of a feature can result in a particular value of another feature or preclude that value. But there are cases where there are no such dependent relationships. The totality of all features and values therefore shows redundancies. This situation is actually desirable, for it allows, at least to some extent, testing for plausibility.
