RE: Sorting and grouping with xsl:analyze

I get the impression that you want the final sort to apply to all the
numbers, not just to each Title-group in turn. That means the second
for-each-group can't be inside the first for-each-group. You need to capture
all the numbers in all the titles in a variable, which you achieve by
wrapping the xsl:for-each-group in xsl:variable, and then apply grouping on
the contents of this variable. Or in fact, distinct-values. So:

<xsl:variable name="all-numbers" as="xs:decimal*">
  <xsl:for-each-group select=".....//Title">
     ...
     <xsl:sequence select="xs:decimal(.)"/>
     ...
  </xsl:for-each-group>
</xsl:variable>

<xsl:perform-sort select="distinct-values($all-numbers)">
  <xsl:sort/>
</xsl:perform-sort>
