+  <p>Interoperability note: earlier versions of this XEP required or recommended the removal of the &lt;private/&gt; element (albeit not of the &lt;no-copy/&gt; hint) by one of the involved servers, but this behavior was considered as a potential security issue as the sender could silently manipulate the delivery of messages, so that the requirement was lifted. However, clients MUST NOT assume that a message without the element was actually routed to all other resources of the account.</p>
   <p><strong>Note:</strong>
     Use of the private mechanism might lead to partial conversations on other devices. This is the intended effect.
     If the private &MESSAGE; stanza is addressed to a bare JID, the receiving server still delivers it according to <cite>RFC 6121</cite>. This might result in a copy being delivered to each resource for the recipient, which effectively negates the behavior of the &lt;private/&gt; element for recipients.</p>
