I have a <div> containing a secondary navigation that should only be  
inserted when there's underlying children.

Something like:

<r:if_children>
   <div id="sidenav">
     <h3>More information</h3>
     <r:children:each>
       <a><r:link /></a>
     </r:children:each>
   </div>
</r:if_children>

would do the trick.
