Possible featuretypes

These lists are available in ModBuddy/Help/Civ5LuaAPI.html.
Alternatively, object metatable can be obtained by calling getmetatable on non-nil object pointer. Then it is possible to iterate over all values stored in __index variable.

local plot = Map.GetPlot(0, 0)
print("Attributes:")
for k, v in pairs(getmetatable(plot).__index) do print(k) end
print("End attributes.");

Is this also possible for:
