| <p>Since protected role types can not be used for externalization, instances of these types are already quite effectively encapsulated |
| by their enclosing team. |
| Based on this concept, encapsulation for protected roles can be made even stricter by the rules of <em>role confinement</em>. |
| On the contrary, even protected roles can be externalized as <em>opaque roles</em> which still expose (almost) no information. |
| Confinement and opaque roles are subject of <a href="s7.html" title="§7 Role Encapsulation" class="sect">§7</a>. |
