And the answer is that this is not possible with xsl:sort in XSLT 1.0, but a
generic sort template can be used as in

There is also EXSLT's <func:function/>, implemented in at least 4 XSLT
processors, including Saxon and Xalan. Randy may wish to read about it at
http://exslt.org/func/elements/function/index.html
The general idea is that it lets one designate an XSLT template (the content
of the func:function element, actually) as an extension function.
