I've been trying to understand HTML Legends by reading
http://www.mapserver.org/output/html_legend.html#sample-site-using-the-html-legend,
and I'm getting it, but I still don't understand the seemingly useless
href calls here and there. On the last screen at the above URL there's
this.
<a href="[leg_layer_name]">[metadata name=WMS_TITLE]</a>
This just sends a layer name to cgi-bin where it dies. Why are these references
here? Is it just to show you can do this, or is it needed for something in the
legend creation?
TIA,
- Bill Thoen
