Culture Tile Yields in Vanilla

[Graan]

I'm trying to make a building add 2 Culture to the yields of Lake and Oasis tiles, using the code below. This works fine in G&K, but not in Vanilla, and I want it to work in both. The mod won't crash, but the yields simply won't change ingame.

<GameData>
	<Building_LakePlotYieldChanges>
		<Row>
			<BuildingType>BUILDING_MAGIC_LIBRARY</BuildingType>
			<YieldType>YIELD_CULTURE</YieldType>
			<Yield>2</Yield>
		</Row>
	</Building_LakePlotYieldChanges>
	<Building_FeatureYieldChanges>
		<Row>
			<BuildingType>BUILDING_MAGIC_LIBRARY</BuildingType>
			<FeatureType>FEATURE_OASIS</FeatureType>
			<YieldType>YIELD_CULTURE</YieldType>
			<Yield>2</Yield>
		</Row>
	</Building_FeatureYieldChanges>
</GameData>

The term "YIELD_CULTURE" does not exist in Vanilla at all, as far as I know. I do know tile yield changes for Culture are possible, as it happens with the Monastery building.

The code below is what I managed to find. Since the Lake and Oasis are respectively a Plot and Feature (not a Resource), this won't do. It's the closest I got, though.

<GameData>
        <Building_ResourceCultureChanges>
		<Row>
			<BuildingType>BUILDING_MONASTERY</BuildingType>
			<ResourceType>RESOURCE_INCENSE</ResourceType>
			<CultureChange>2</CultureChange>
		</Row>
		<Row>
			<BuildingType>BUILDING_MONASTERY</BuildingType>
			<ResourceType>RESOURCE_WINE</ResourceType>
			<CultureChange>2</CultureChange>
		</Row>
	</Building_ResourceCultureChanges>
</GameData>

Is there any way to make this work?
