22. Extending the UML

Stereotypes can be used to extend the UML
notational elements.
Stereotypes may be used to classify and
extend associations, inheritance
relationships, classes, and components.
Examples
Class stereotypes: interface, exception, server
page
Association stereotypes: identifying, nonidentifying
Dependency stereotypes: include, extend
Component stereotypes: subsystem
