<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="&sect;2.1&nbsp;playedBy relation" class="sect">&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.
</p>
<div class="note">
<h5>Note:</h5>
Item 4.
&mdash; within the given restriction &mdash; 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="&sect;1.5&nbsp;Team and role nesting" class="sect">&sect;1.5</a>.
