The WixExtensions extend the compiler/linker and provide embedded .wixlibs to do provide functionality that is not built-in. For example, the WixUtilExtension adds custom elements so you can do things like manipulate XML files (aka: XmlFile and XmlConfig). When you use one of those custom elements WixUtilExtension, also brings in the necessary setup code (as part of a .wixlib) to ensure the custom action (because MSI does not support modifying XML files natively) is correctly configured.
The WixUIExtension is basically the container for a very large .wixlib that provides all sorts of different UI functionality (becuase MSI dos not provide full UI by default). You reference one thing in the WixUIExtension using a <UIRef/> and the extension provides the .wixlib that implements all the UI. Basically, the WixExtensions encapsulate the complex code and makes it look really easy.
