dmerrill: Case insensitive sorting in XSLT is relatively simple. Consider this simple XSLT fragment:

<xsl:variable name="ucletters"
  select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'"/>
<xsl:variable name="lcletters"
  select="'abcdefghijklmnopqrstuvwxyz'"/>

 <xsl:template match="entry">
  <xsl:sort select="translate(title, $lcletters, 
$ucletters)"/>
  <-- Do stuff -->
</xsl:template>

Which will process something like

<entry>
  <title>Foo</title>
  <title>Bar</title>
  <title>Baz</title>
</entry>

In <title> order, not document order.
