With XSLT/XPath 1.0 all you can compare with > and < are numbers so you 
need to do
   number(translate('2007-07-09', '-', '')) > 
number(translate('2007-07-08', '-', ''))
that way you compare the numbers 20070709 and 20070708.

format-date and format-dateTime are part of XSLT 2.0. Only Saxon and 
Altova so far have products implementing XSLT 2.0. And format-date and 
format-dateTime are not for comparing numbers, they are there to format 
date respectively dateTime values for output. So doing e.g.

     <xsl:for-each select="('2007-07-01', '2000-01-01')">
       <xsl:value-of select="(format-date(xs:date(.) , '[MNn] [D], [Y]', 
'en', (), ()), '&#10;')"/>
     </xsl:for-each>

outputs

July 1, 2007
January 1, 2000

with an XSLT 2.0 processor like Saxon.
