Interesting ! The above seems to work well if I embedd the <co.../> elements
into my program text. However, if I xinclude the program text and provide
an <areaspec/> to generate the map it doesn't.

That might be the part that's provided via those extensions that aren't provided
by xsltproc.

Thanks for the help !
