Bart,

It's been about 3 years since I fought this battle, but let me try to help
you anyhow.

I think what I ended up doing was manufacturing the correct logic by using
the METADATA block in the Mapfile. For example, I wanted to include a radio
for "active" layer in the legend, but not for all vector layers (or
something like that). Having no "isnotnull" I had to create an "isnull"
scenario that worked. 

Something like this in the .map:
METADATA
	"NoID" "T"
	"DataLayersID" "1"
	"wms_title" "Judicial"
	legend_order "3000"
END

Something like this in the htmllegend template:

[if name=NoID oper=isnull]
<input type=radio name=idlayer value=[leg_layer_name]  onclick=SetQ2Radio()>
[/if]

Like I said, it's been awhile, but maybe you can use that as a jumping off
point. If you are interested in the complete htmllegend template and Mapfile
let me know.

Hi list,

since there is no [else] tag in Mapserver HTML legends, why is there no
"isnotnull" operator besides the "isnull" operator?

Best regards,
Bart
