[BNW] How to allow faith purchase of Great People through policies?

[nguyenforthewin13]

I've been searching through the game's code in the BNW and G&K to find the code that allows the purchasing of Great People upon the completion of a policy tree, but I can't find it. I'm trying to make a policy that allows the purchase of all Great People (sounds overpowered, I know, but it's part of an ideology tree overwrite of Order I'm doing to make a religious ideology tree for a scenario). I checked CIV5Policies and CIV5PolicyBranchTypes, but no game. Please help.

Alright, to anyone who might read this, I looked into it myself and found a post from another user on this forum stating that apparently this is impossible through XML. There is no way through XML to create a policy to allow the purchase of Great People or otherwise edit the current policies which allow this function. The actually coding allowing for this is wrapped up somewhere deep within the game's DLL. Unfortunate.
