BNVs are volumes that have a pathfinding grid assigned to them.
The grid itself is in the RAW, while its overall parameters are in the DAT.

BNVs are axis-aligned boxes, so the coordinates of two opposed corners define a BNV completely.
It makes sense to specify a "minimal" corner and a "maximal" corner, in that order.
Still unknown and probably important
The grid usually "bleeds" outside the (x,z) extent of the BNV.
The amount of bleeding is defined by the grid's size (in tiles) and by the size of a tile.
The only unknown is the offset of the grid with respect to the center of the BNV's base.
I suppose it's specified by some of the unknown floats. Didn't check.
I don't remember seeing a rotated BNV, but there could be some of those.
