 <p>Contexts <a name="a001"></a> in Scalability Protocols provide for isolation of protocol-specific

+<p>For example, a <a href="../proto/rep.html">REP</a> server may wish to allow many requests to be serviced concurrently,
 even though some jobs may take significant time to process. Contexts provide for this ability.</p>
 <p>Not all protocols have contexts, because many protocols simply have no state to manage.
 The following protocols support contexts:</p>
 <ul>
-<li><a href="../../proto/rep.html">REP</a></li>
-<li><a href="../../proto/req.html">REQ</a></li>
-<li><a href="../../proto/respondent.html">RESPONDENT</a></li>

+<li><a href="../proto/surveyor.html">SURVEYOR</a></li>
+<li><a href="../proto/sub.html">SUB</a></li>
 </ul>
 <p>For these protocols, the socket will also have a single, default, context that is used when
 performing send or receive operations on the socket directly.</p>
 <p>Other protocols are stateless, at least with respect to message processing, and have no use for
-contexts. For the same reason, <a href="../../api/sock.html#raw-mode-sockets">raw</a> mode sockets do not support contexts.</p>

 Contexts provide a superior solution, as they are much easier to use, less error prone, and allow
 for easy control of the amount of concurrency used on any given socket.</p>
