Ok, I downloaded the modmod, and looked at the afghanistan file set.
1. Schema files are no longer needed here.
2. In the CIV4CivilizationInfos.xml
3. in the CIV4ColorVals
4. in the CIV4GameText.xml
5. in the CIV4LeaderHeadInfos.xml
6. in the CIV4PlayerColorInfos.xml
1. Schema files are no longer needed here.
2. In the CIV4CivilizationInfos.xml
change "x-schema:Afghanistan_CIV4CivilizationsSchema.xml → "x-schema:../../../XML/Schema/C2C_CIV4CivilizationsSchema.xml"
change BUILDINGCLASS_CULTURE_HUMAN → BUILDINGCLASS_CULTURE_NATIVE
change BUILDINGCLASS_CULTURE_HUMAN → BUILDINGCLASS_CULTURE_NATIVE
3. in the CIV4ColorVals
change "x-schema:Afghanistan_CIV4InterfaceSchema.xml" → "x-schema:../../../XML/Schema/C2C_CIV4InterfaceSchema.xml"
4. in the CIV4GameText.xml
change encoding="ISO-8859-1" → encoding="utf-8" (not an important step I think)
after "http://www.firaxis.com" add a space then xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.firaxis.com ../../../Xml/Schema/Civ4Gametext.xsd"

5. in the CIV4LeaderHeadInfos.xml
change "x-schema:Afghanistan_CIV4CivilizationsSchema.xml" → "x-schema:../../../../XML/Schema/C2C_CIV4CivilizationsSchema.xml"
Maybe you need to add the missing eras to the music section for this one compare it with any CIV4LeaderHeadInfos.xml in core C2C Custom_Civilizations module.

Rince repeat for all civs in the modmod and I think that should do it.
