I did a slightly different take on this and assumed that you would want to
collect all of joe's preferences together, like this:

 Ann says: "Pears."
 Joe says: "Apples, Bananas,Oranges."

Even if this is not what you really want, it's interesting to see how it
works out.  I have not completely handled putting in commas everywhere
except a period for the last item - I leave this to the reader.  I also
haven't translated the first character of the name to upper case - Jenni
covered that.  I also sorted the result by name.  The solution is very
compact without those refinements:

==========================================================
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method='text'/>

<!-- key for using the Muenchian method of getting unique node sets-->
<xsl:key name='wrappers' match='wrap' use='name(*)'/>

<!-- Elements with unique person names -->
<xsl:variable name='unique'

select='/root/wrap[generate-id(key("wrappers",name(*))[1])=generate-id(.)]'/
>

<xsl:template match="/">
 <xsl:for-each select='$unique'>
  <xsl:sort select='name(*)'/>
  <xsl:variable name='theName' select='name(*)'/>
  <xsl:value-of select='$theName'
  /> says: <xsl:for-each select='key("wrappers",$theName)'
   ><xsl:value-of select='normalize-space(.)'
  />, </xsl:for-each><xsl:text>&#10;&#13;</xsl:text>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
========================================================

The slightly odd formatting is an easy way to control the output format
while still having short line lengths in the stylesheet (better for
emailing), and the &#13; character reference is necessary on my (Windows)
system to get the line feed to display.  Here is the result (I added another
person, bob, to the data, just for fun):

===========================
ann says: Pears,
bob says: Peaches,
joe says: Apples, Bananas, Oranges,

===========================

This was interesting because the usual examples for getting unique node-sets
assume you know what the target elements are named, but not in this case.
