If a new symbol is defi ned for a stereotype, then it can be used instead of the
UML notation. A third notation option lets you mix the two symbols. Figure 3.87
uses the system process element, which is a stereotype of the use case, to demonstrate
the notation variants.
A profi le is a special package that groups stereotypes. Using a profi le is the
only way to assign a stereotype to a model and use it there ( Figure 3.88 ). There
are standardized profi les, such as the UML Testing Profi le [53], or the UML Profi le
for MARTE systems [49]. This profi le includes stereotypes that defi ne test vocabulary
(e.g., test case or test context ) to describe a test model. Chapter 5 describes
the SYSMOD profi le that introduces the SYSMOD approach in this book.
