attribute class

Another attribute class used in the example is type variable, parts 9 and 10 being shown in Figure 6.33.

By convention, attribute classes end with "Attribute" in their name.

So, in the earlier example, "(things that are) taller than 26 inches" is the attribute class and "people" is the reference class.

Consequently every attribute class name should end with this string, but it is legal to define an attribute without the -suffix.

F is called the "reference class" and G is the "attribute class" and I is the individual object.

All elements which represent links or associations between one element and another do so using a common set of attributes, and are thus regarded as forming the attribute class pointer.

In the same way, the attribute class name contains all elements used to represent various kinds of name, all of which share the attributes key (used to specify an external database key or other identifier for the object named) and reg (used to specify a regularized form of the name).
