I understand that part, but what I am confused about (probably because I am doing Civ4 modding, writing a weekly status report for work, developing class and sequence diagrams for my project at work, etc. all at the same time) is why they are allowed to use warriors... wait a sec, the barbarian entry in the file is missing the:
Code:
<Unit>
<UnitClassType>UNITCLASS_WARRIOR</UnitClassType>
<UnitType>None</UnitType>
</Unit>
entry,

. Ok, it now all makes sense...
Yep, that is correct, then of course I have never had a reason to edit the Civ4CivilizationInfos.xml file
