In the concept modeling interpretation of the UML standard, a class is a set or collection of individual things called members. The members of a class in a concept model are either things that exist in the real world around us, or things we can imagine to exist, such as unicorns. For example, depending on the stated scope of a concept model, the members of a Chair class would include the one you sit upon to do your work, or the one in a warehouse ready to be shipped to a customer.

UML Classes

The owner is no longer shown by default on a UML Class in Concept Modeling diagrams.

Anonymous Classes

An unnamed UML Class represents an anonymous class expression, used for defining conditions, including domains and ranges.

Complex Chain

Importing a complex chain of restrictions no longer shares anonymous UML classes among multiple concept models.

When you hover over the newly created anonymous class, description of each anonymous class appears in the containment tree, specification window, and diagram.
