Where can I find xml data for DLC civs?

[Narvana]

For example, polish civ's folder (in DLC section) have only xmls involing icons.

 

[LeeS]

C:\Program Files (x86)\Steam\SteamApps\common\Sid Meier's Civilization VI\DLC\Poland_Jadwiga\Data

Poland_Jadwiga_ConfigData.xml
Poland_Jadwiga_GameplayData.xml

similar for the other DLC, each within its own folder. except fopr Australia DLC which uses file names of AUstralis_Civilizations, Australia_Config, Australia_Features, etc.
