Editing leader traits

[peteandbill]

Is there a way to edit leader traits beyond the xml and/or add more tags to the leader trait xml? I'm trying to make a trait that gives extra yield to improvements along rivers, but so far i don't think i can do that just through xml. I couldn't find any lua files concerning leader traits though

It's the same answer as pretty much every other change anyone has ever suggested:

1> No, it's not possible to do in XML.
2> Yes, it's possible to do in Lua...
3> ...but the AI won't have any idea how to use it...
4> ...and it'll look sloppy, since the interface won't handle it well.

Now, a lot of times there's a way to still get most of you want, just using XML. For instance, you want a trait to have a certain ability, but maybe traits can't HAVE that ability. But maybe buildings CAN have that ability, so all you need to do is create a unique building for your civ that has that extra ability in addition to its normal effect.
