These proposals make the same changes to both C++ and C and remove a restriction on standard attributes appearing multiple times in the same attribute list. We could warn on the duplicate attributes, but do not. This is for consistency as we do not warn on attributes duplicated within the attribute specifier sequence. If we want to warn on duplicated standard attributes, we should do so both for both situations: [[foo, foo]] and [[foo]][[foo]].
