perhaps the question is if the getLegendGraphic request supports a title
in the legend. i assumed that it would since the documentation for the
css plugin states "GeoServer uses the title in auto-generating legend
graphics".
i have tried adding a title element to several fields -- and have names
on them as well. i never get any sort title on my legend, below is the
url for the graphic, and the style is attached. am i perhaps missing a
parameter in the request?
