    xmlns:DateFunctions="urn:DateFunctions"
    exclude-result-prefixes="DateFunctions">

    <xsl:template match="/">
        <xsl:for-each select="Company/Products/Product">
            <xsl:variable name="SingleQuote">'</xsl:variable>
            <xsl:comment><xsl:value-of select="concat('The product, ', $SingleQuote, Sku, $SingleQuote, ', was processed at ', DateFunctions:GetDate('dd/MM/yyyy HH:mm:ss'))"/></xsl:comment>
        </xsl:for-each>
    </xsl:template>
