Unfortunately, attributes that contain XPath expressions (such as the
select attribute of <xsl:sort>) are never attribute value templates.
The traditional way around this is to use something like:

  <xsl:sort select="@*[name() = $orderBy]" order="ascending" />

where $orderBy is 'forename' or 'surname'. In other words, select the
attribute whose name is specified by $orderBy.

Cheers,
