<p>If the super-class of a role is again a role it must be a direct role of
an enclosing team
This rule is simply enforced by disallowing type anchors in the
<code>extends</code> clause
(see <a href="s1.2.2.g.html" title="&sect;1.2.2.(g)&nbsp;Legal contexts"
class="sect">&sect;1.2.2.(g)</a>).
As an effect, the super-class may never be more deeply nested than the sub-class.
