| <p>Anchored types for externalized roles may be used in the |
| following contexts: |
| |
| </p> |
| <ol> |
| <li>Declaration of an attribute</li> |
| <li>Declaration of a local variable</li> |
| <li>Declaration of a parameter or result type |
| of a method or constructor |
| </li> |
| <li>In the <code>playedBy</code> clause of a role class |
| (see <a href="s2.1.html" title="§2.1 playedBy relation" class="sect">§2.1</a>). |
| </li> |
| </ol> |
| <p>It is not legal to inherit from an anchored type, since |
| this would require membership of the referenced team instance, |
| which can only be achieved by class nesting. |

| Item 4. |
| — within the given restriction — admits the case where |
| the same class is a role of one team and the base class for |
| the role of another team. Another form of nesting is |
| defined in <a href="s1.5.html" title="§1.5 Team and role nesting" class="sect">§1.5</a>. |
