Unlike other XML files, these files can have any name and still be recognized by the game. Most epic game files are Civ4GameText_*, but a file could be named anything. For example, Assets\Text\XML\Buildings.xml would be recognized by the game without any SDK changes. This can be done with no other type of XML file.
