I get an odd error when I try to do that.

If I have this:

<xsl:for-each select="//menuItem[ancestor-or-self::menuItem/pageID =
$pageID]"> 
                <xsl:sort select="substring(lastUpdate,1,4)"
order="descending" /> <!-- year  -->
                <xsl:sort select="substring(lastUpdate,6,2)"
order="descending" /> <!-- month -->
                <xsl:sort select="substring(lastUpdate,9,2)"
order="descending" /> <!-- day   -->
                <xsl:if test="position() &lt; $numberOfItemsToList">
                        <xsl:call-template name="createItem" />
                </xsl:if>
</xsl:for-each>

It seems to work. But once I add in a value-of statement:

<xsl:for-each select="//menuItem[ancestor-or-self::menuItem/pageID =
$pageID]"> 
                <xsl:sort select="substring(lastUpdate,1,4)"
order="descending" /> <!-- year  -->
                <xsl:value-of select="pageID" />
                <xsl:sort select="substring(lastUpdate,6,2)"
order="descending" /> <!-- month -->
                <xsl:sort select="substring(lastUpdate,9,2)"
order="descending" /> <!-- day   -->
                <xsl:if test="position() &lt; $numberOfItemsToList">
                        <xsl:call-template name="createItem" />
                </xsl:if>
</xsl:for-each>

I get this error:

XsltException: 'xsl:sort' cannot be a child of 'xsl:for-each' element.

Which is confusing, as it works just fine with xsl:sort being a child of
xsl:for-each UNTIL I add in a value-of statement.
