Referencing a lookup table

Hi !

I am relatively new in the world of XML and XSL, so my problem has probably 
been adressed before. I have been looking in the archive but couldn't find any 
solution.
Well, the point is that I have some XML-tags added to an original XML message. 
The result looks like this:

<document>
   <!-- original tags -->
   <policy>
      <cover>
         <fundcode>1</fundcode>
         <amount>120</amount>
         <some_other_stuff/>
      </cover>
      <cover>
         <fundcode>2</fundcode>
         <amount>80</amount>
         <some_other_stuff/>
      </cover>
   </policy>
   <!-- addes tags -->
   <funds>
      <fund>
         <code>1</code>
         <desc>Fund 1</desc>
      </fund>
      <fund>
         <code>2</code>
         <desc>Fund 2</desc>
      </fund>
   </funds>
</document>     

I want te create a XHTML where I select form the cover node the funds including 
the corresponding description in the added tags section. 
I have been struggling with all kinds of combinations of value-of and for-each 
elements but so far no result. Is there anybody who can help me ?

Kind regards,
Gregor Sips
