To be specific, I want the result of:

Since a normal variable doesn't change, the sort will have no effect (but I'm
sure you already figured this out).
with parameter sortkey:
<xsl:with-param name="sortkey" select="@name"/>
If you pass select="@name", it will evaluate "@name" in the context of the
with-param, not in the sort. So you probably want to change this to:
<xsl:with-param name="sortkey" select="'@name'"/>
which will pass the string '@name' to be evaluated later.
to be equivalent to:
<xsl:sort select="@name" order="descending"/>
To evaluate the string, you need to use some kind of extension function. Look
in the documentation of whatever processor you use; it will probably look
like:
<xsl:sort order="descending" select="xxx:evaluate($sortkey)"/>
The 'xxx' will be associated with an extension namespace specific to your
processor. The evaluate() function will take the string $sortkey and
evaluate it as an XPath expression.
