[mapserver-users] HTML Legends - What Good Are They?

[Bill Thoen]

I've been searching the 'net and asking questions here for the last two 
days on HTML Legends, and outside of the standard MS documentation 
(which has some very confusing bits in it for one who's unfamiliar with 
the way it works) I've not found anything relevant on this topic except 
my own questions echoed back at me from nabble and some 
interestingly-titled documents that are inaccessible because they were 
on the old MS website. And so far the forum's been silent on the issue 
as well.

But I have discovered one old message hinting at clever ways to use 
nested [if] statements with custom metadata variables to make a very 
useful layer control with collapse and expand features and more. I want 
to learn more about that but I'd like to skip the time-consuming process 
of learning by trial and error.

So can anyone point me to some documentation that goes into more detail 
about what HTML Legends can really do or direct me to one or two URLs 
that demonstrate some advanced techniques with nested [if] ...[/if] 
blocks and custom metadata variables?
