I found myself wanting more than 10 callouts and wanting them too look
crisp in pdf, so I made some svg callouts (and used Batik to convert
them to other formats for use in html). I'm actually using the pdf
version of the callouts in my output because XEP wasn't rendering the
svgs for me. It renders other svgs fine, but I don't have time right now
to mess with it. However, it occurs to me that a better solution would
be to have the DocBook xsls write the svg directly into the fo. In fact,
to make these, I just made one svg with a circle and a character in the
middle, then looped 99 times using sed to number the callouts. Be aware
tho that I manually tweaked #1 and #4 just slightly to make them appear
more centered and legible.
In any case, if someone wants to use them as is or work with this some
more, e.g. futz with the sizing to get it just right...mine are a little
bigger than the current callouts or incorporate them into the DocBook
xsls so they put the svg directly into the fo, feel free:

Btw., if you ever manage to use all 99 callouts in a programlisting, I'd
love to see it :-)
