Well, for that, I'd say we could tackle it in a number of ways: - have a special function interface that allows for bounds compuatation - just try to transform the bounds and get the bounds of the result I guess what I'm proposing is not really full blown Expression, but more of PropertyName/Function alternative like in the WFS 1.1 specification (look at QueryType). > Are you still interested in perusing these ideas? I ask because I am > having similar fun with the symbolizer interfaces right now. As a matter of fact I am, I just got stuck on that thread due to negative feedback. But mind, I am on a personal basis, this means weekend time for me, not workweek one. But if we're pushing this togheter, it seems very doable to me.
