Class attributes are properties of a class that are shared amongst all instances of that class. They are not tied to any specific instance variable. These attributes can be observed externally, such as accessing a public variable or calling a method of the class. Aggregation with another class is typically represented using a relationship, not an attribute. UML diagrams can represent class attributes using the notation of underlining the attribute name.
