<strong>Note 3:</strong> In order to work over XMPP servers that do not maintain message order, a <strong>nr</strong> attribute is available on the
<strong>chunk</strong> element. The first chunk reports a <strong>nr</strong> of zero. Each succcessive chunk reports a <strong>nr</strong> that is
incremented by one. In this way, the receiver can make sure to order incoming chunks in the correct order.
