+    <p>To indicate support for inlining stream resumption into the authentication process, the server adds a &lt;sm/> element in the namespace "urn:xmpp:sm:3" to the &lt;inline/> element of SASL2.</p>
     <p>If the client wishes to resume an existing session it, it simply includes the &lt;resume/> element defined by this specification in the SASL2 &lt;authenticate/> element.</p>
     <p class="box">Note: If the client included a &lt;resume/> element in its SASL2 &lt;authenticate/> element, that MUST be processed first by the server. If that resumption is successful, the server MUST skip resource binding (a resumed session already has a resource bound) and MUST entirely ignore the &lt;bind/> request that might also be inlined in the &lt;authenticate/> element.</p>
     <p>&xep0388; mandates that the &lt;success> element is immeditaly followed by stream features. If a former stream has been successfully resumed using this specification, the stream is considered re-established immediately after the &lt;success/> element instead and stream features MUST NOT be sent in this case.</p>
