A tooltip is not displayed whenever a anchor ("a" element) has the "xlink:title" attribute  set.
Batik already displays the contents of "title" and "desc" elements as tooltips, as suggested by the SVG specification , so I'd say we should also display the link title.
I'm not sure how precedence should be handled (when a given link has "xlink:title" attribute and child "title"/"desc" elements), but it is suggested  that "xlink:title", when set, should take precedence over the other.
A current workaround consists of adding a "title" child element to the anchor with the same content as the "xlink:title" attribute, which is then rendered by Batik. A test case with this idea was implemented  during experiments in order to force a pointer cursor in ASV3: one would expect a tooltip when hovering on the blue (leftmost) circle.
