When modules outside the packages attempt to use this content, the EDK II build system must break with an error regarding content not found. The four sections, Includes, Ppis, Guids and Protocols headers will be the keyword, Private, following the architecture modifier. If Private is not present, then the content is usable by modules outside the package.
