When an object has several regions of text that actually present a single text-stream, such as text broken into multiple columns, it should expose this relationship to accessibility aids through the use of NAVDIR_NEXT and NAVDIR_PREVIOUS ordering. In addition, it should set the STATE_TEXT_CONTINUED attribute on all but the first region, and STATE_TEXT_CONTINUES attribute on all but the final region.
