Sorry perhaps I misunderstood your question. All of my comments were
about Batik's SVG browser 'Squiggle'. If you want to know how to display
a toolTip with FireFox or IE6 I suggest you ask those developers.

I was testing using (on linux, mac use build.sh):
build.bat squiggle samples/tests/spec/structure/toolTips.svg
Squiggle simply wraps the JSVGCanvas.

Batik/JSVGCanvas doesn't try to mimic any browser behavior, it tries
to properly implement the SVG standard.
