Hi Olivier,

(CCing the mapbuilder and mapserver lists because they might be 
interested in this)

I'm sorry, but I have never tried to do this. Actually, I don't think 
it's possible because a Context file lacks some important information 
for mapserver, like where a layer's data is physically stored on disk, 
postgis, etc. The map file does not only configure layers like a Context 
doc, but it is also the main configuration source for the mapserver 
rendering engine.
That being said, there might actually be some WMC support in mapserver, 
and therefore I have CC'ed this message to the mapserver list too. Maybe 
one of the Mapserver users/developers can comment on this and enlighten 
Olivier and the rest of us?

I have not yet committed my custom legend to trunk. I might do so when 
it is more or less finished, though I think it should be more feasible 
to put it somewhere on the mapbuilder site as a legend xsl example, then 
to trunk as another legend renderer again. I think legend xsl/js files 
are typically widgets that can be changed and adapted by any user, and 
many users will have different opinions and needs about how a legend 
should look and behave. However, as an example of an advanced legend 
(ahum, if I may say so...) it might be good to post it somewhere.
However, if other MapBuilder developers disagree with me and think the 
addition of my legend js/xsl code to trunk would be a good idea, I will 
commit it.
If you would like to see my code, I can send you the files of course.

Regards,
Vincent.
