How do I link text in Civilopedia?

[Craig_Sutter]

I did the following xml code:

<Language_en_US>
		<Row Tag="TXT_KEY_TRAIT_CALLING_THE_FYRD">
			<Text>Wessex melee units have +1 movement points and receive the free promotion Discipline. [LINK=MINOR_CIV_WIHT]Wiht[/LINK] is a subkingdom of Wessex.</Text>
		</Row>
		<Row Tag="TXT_KEY_TRAIT_CALLING_THE_FYRD_SHORT">
			<Text>Calling the Fyrd</Text>
		</Row>
	</Language_en_US>

I saw a similar method with [LINK=IMPROVEMENT_POLDER]Polder[/LINK] and expected that the method would link to text in Civilopedia somehow... but perhaps it doesn't.

Is such a link possible... do I link directly to the text key instead?
