EB Faction in Export_Descr_Unit.txt

Is there a mapping of the EB faction names to the original factions? I would like to see what units each of the EB factions can use but the original faction names are used in the Export_Descr_Unit.txt file, even for new EB units.

Also, how can I permit a specific type of wall (say large stone) to be used for a barbarian tribe (e.g. Casse)? I updated the Export_Descr_Buildings.txt and Export_Buildings.txt files but that apparently is not enough.

Thanks in advance.

Anyone know about the wall question?
