XML Full Merge

How do you do a full merge in cocoon??

Full merge, occurs when you need to combine two documents with slightly different structures and data into a third document. For example, you might want to combine a document containing employee names with a similar document containing employee addresses. You need some way to link the records in the two files, probably through an ID field. The following document fragments illustrate a full merge.

Document 1:

<employees>
   <employee id="1" class="super">
      <lastname>Smith</lastname>
      <firstname>Marsha</firstname>
   </employee>
</employees>

Document 2:

<employees>
   <employee id="1">
      <address>115 Marshal Rd., 
      Greenville, MN 39281</address>
   </employee>
</employees>

Merge Result:

<employees>
   <employee id="1" class="super">
      <lastname>Smith</lastname>
      <firstname>Marsha</firstname>
      <address>115 Marshal Rd., 
      Greenville, MN 39281</address>
   </employee>
</employees>
 
I found something (http://www.fawcette.com/archives/premier/mgznarch/xml/2001/06jun01/rj0103/rj0103.asp) that does it using and xslt. But cocoon does like to support document() function in xslt. 
So how can this be done?
