Sorting values that contain spaces

Given input like this (a list of SQL table names):

<tables>
  <table name="Claim"/>
  <table name="Claim Aggregate Queue"/>
  <table name="Claimant"/>
  <table name="Claim Association Fact"/>
</tables>

And XSL like this:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <xsl:template match="tables">
    <xsl:for-each select="table">
      <xsl:sort select="@name"/>
      <xsl:value-of select="@name"/><xsl:if test="not(position() = 
last())"><xsl:text>, </xsl:text></xsl:if>
    </xsl:for-each>
  </xsl:template>

</xsl:stylesheet>

I get this:

Claim, Claim Aggregate Queue, Claimant, Claim Association Fact

I would like to get this:

Claim, Claim Aggregate Queue, Claim Association Fact, Claimant

How can I get that?

I checked the FAQ and various archives of the list, but I didn't find 
anything on target.

Thanks.
