This nice explanation illustrates extremely well why we need to use a generic sort
template in this case.

While any use of a generic sort() will be natural, any attempt to use xsl:sort for
cases far from the most trivial -- these will look perverted and totally
incomprehensible to anybody but their author.

This is because xsl:sort needs a sort-key as ***one*** expression to be specified as
the value of its select attribute.

Contrary to this, a generic sort template leaves to the caller-supplied template the
definition of what a sort-key is and how sort-keys should be compared.
