[mapserver-users] HTML Legends -- Need Elightment

[Bill Thoen]

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,
