I think Michael wants a hot spot for each link /whithin/ the SVG. For
this, he needs to know where those links in the SVG are (NB: in SVG,
you can embed <a href="...">...</a> elements, they are allowed in the
definition, and browsers honour them)

I think Michael wants a more fine-grained approach; if I understand
you correctly, the whole SVG image would be just one button, right?
