         <p>Security considerations related to object persistence via publish-subscribe are described in <cite>XEP-0060</cite> and <cite>XEP-0223</cite>.</p>
         <p>The client needs to make sure that the server actually supports the "http://jabber.org/protocol/pubsub#publish-options" feature, before relying on it. If it's not supported, the client should configure the '&namespace;' node first (see <cite>xep-0060</cite>), before adding any bookmarks.</p>
