public String getNode() {
        return node;
    }
<p>
Returns the node attribute that supplements the 'jid' attribute. A node
is merely something that is associated with a JID and for which the JID
can provide information.
</p>
<p>
Node attributes SHOULD be used only when trying to provide or query
information which is not directly addressable.
