In UML modeling, you can add detailed information to
the model elements in your models. This text could include any information
that you want documented, such the role, purpose, or behavior of
the model element.
Before you can document a model element, you must
display the Properties view in the Modeling
perspective.
To document a model element:
- In the diagram editor, click a model element.
- In the Properties view, click the Documentation tab.
- On the Documentation page, type the appropriate text.
