I would like to see this also, exactly as peter described it (using
+ to seperate each x,y pair). What we really need to define are the
semantics for the browser ISMAP="point" rect poly??? I'm not sure how
to do this in a generic way (do we also need "sound" "video"??).
Maybe instead of telling the browser the type of selection the browser
should tell the server: http://server/europe?poly+x,y+x,y...
But maybe the ISMAP should still have a hint about what's expected?
