--- Comment #10 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Not just a note, above that 9.9 note there is a normative text: "If a substring-range appears in an array-section, each element is the designated substring of the corresponding element of the array section." If substring-range can't be applied to array-sections, then this sentence makes no sense.
