       <p>When the XMPP Council votes to advance the XEP to a status of Draft, the XMPP Registrar shall generate official names for all namespaces specified in the XEP. The following considerations apply:</p>
       <ol>
         <li>Each name shall adhere to the format defined in &xmppurn;.</li>
-        <li>The "ShortName" and "SubName" strings may be determined in consultation with the author(s) of the XEP.</li>
+        <li>The "ShortName" string shall be unique within the XMPP URN tree and any "SubName" strings shall be unique within the scope of the ShortName.  All such strings should be relevant and memorable, and may be determined in consultation with the author(s) of the XEP.</li>
         <li>Each name shall be checked against the registry of existing names located at &NAMESPACES; to ensure that no duplicate names are issued.</li>
         <li>The XMPP Registrar shall assign all XMPP URNs directly and shall not assign secondary responsibility for management of any sub-trees.</li>
       </ol>
