E.g., to sort <row>s by their 'time' attribute, this works:

<xsl:template match="parent-of-row">
<xsl:apply-templates select="row">
<xsl:sort select="@time">
</xsl:apply-templates>
</xsl:template>

To parameterize the name of the attribute value for sorting, you can
do something like this:

<xsl:param name="sort-key-att-name" select="'time'"/>

<xsl:template match="table">
<xsl:apply-templates select="row">
<xsl:sort select="@*[local-name()=$sort-key-att-name]"/>
</xsl:apply-templates>
</xsl:template>

When you invoke the transformation, pass it the 'sort-key-att-name'
parameter value (which should be one of the attribute names on <row>).
