[xsl] Finding last node in recursive tree

["Woosley, David" <David.Woosley@xxxxxxxx>]

Assume my XML document contains one or MORE hierarchies of 'dataset' nodes,
like this:
			
<report>
   <stuff/>
   <dataset>
      <dataset>
         <stuff/>
      </dataset>
      <dataset>
         <stuff/>
      </dataset>
   </dataset>
	<stuff/>
   <dataset>
      <dataset>
         <stuff/>
         <dataset>
            <stuff/>
         </dataset>
         <DATASET>
            <stuff/>
         </dataset>
         <stuff/>
      </dataset>
   </dataset>
	<stuff/>
</report>

The 'dataset' levels will vary in depth.  Other elements will be sprinkled
among the 'dataset' nodes.  How can I determine when I am at the beginning
of the very LAST 'dataset' node (the node in caps above), regardless if its
depth?

Many thanks,

David Woosley
