I've used xslthl.jar with 1.72.0 and Saxon 6.5.5. I think it is the best
approach.
Can you provide more details on how you are using it?

Ah, glad to see that someone got it going.[1] :-)

Yeah, here is my Saxon6.5 attempt:

$ ./highlight-fo.sh -o ch09.fo ch09.xml

potentially highlighting? false
FOOO!

(I tried building a JAR from the CVS repo of XSLTHL and using a Saxon8
