Xsl:sort attribute value templates for select and order

Question

I've tried the xdk_java_9_0_1_0_0.tar.gz update today and for that the reported bugs are still there : one urgent (quite a stopper for us) is this one
<xsl:template match="/resultlist">
<xsl:variable name="sortorder">descending</xsl:variable>
<xsl:variable name="sortfield">name</xsl:variable>
<xsl:for-each select="result">
<xsl:sort select="./{$sortfield}" order="{$sortorder}"/>
<xsl:value-of select="./index"/>,<xsl:value-of select="./name"/>
</xsl:for-each>
</xsl:template>
still it does not replace {$sortfield} and {$sortorder}.

Answer 1

This is known bug 1798018 in the Oracle XSLT processor.
The only workaround I can think of is to use <xsl:choose> to optionally use different <xsl:for-each> blocks, one with order="ascending" and one with order="descending" as literal values.
