Note that Batik uses tooltips to expose <title> information, too.  (And
puts rootmost <svg>’s <title> in the title bar of the window.)

Ah, I interpreted the “should” as “should, according to what the specs
say”.  I don’t know if any UA renders xlink:title="" attributes as
tooltips.

Assume one is there, <title>Test document</title>.  (It’s not important
for what my example was demonstrating.)

It should be used as title="" is used in HTML, I guess.

Because an xlink:title="" attribute only makes sense on an element that
also has an xlink:href="", as its purpose is to give a title for the
xlink:href="".
