Variable substitution

[Daniel Morissette]

I can confirm that %variable% substitution doesn't work for the label 
text parameter, but it should be possible to set it using the 
"map_layer_..." URL syntax as described in:

http://mapserver.gis.umn.edu/docs/reference/cgi/controls

Look for section "Changing map file parameters via a form or a URL" at 
the end of this document.
