Hi Andrew,

let me try what came to mind second ;)
Here's my go on it in a single XPath statement. A bit less well-suited 
for educational purposes. It shows nested for-loops in XPath, casting, 
use of sequences+separator and some ways how not to code (it is exactly 
an example of good programming practice ;)
<xsl:stylesheet version="2.0"
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
   xmlns:xs="http://www.w3.org/2001/XMLSchema";>
 
   <xsl:output method="text" />
   <xsl:template match="/" name="main">
       <xsl:value-of select="
           for $i in reverse(1 to 99)
           return for $j in
               (' on the wall.',
               '.&#10;Take one down, pass it around',
               ' on the wall.&#10;' )
                 
               return concat
                   ($i - xs:integer(ends-with($j, '&#10;')),
                   ' bottle', if ($i = 1) then '' else 's',
                   ' of beer', $j)
       " separator="&#10;"/>
     
   </xsl:template>
</xsl:stylesheet>
