This document contains two buttons, "Story" and "Weather." When either of the buttons is selected, the corresponding selection is played. The <seq> tag allows for only one of the buttons to be selected at a time. On the other hand, the <par> tag allows the captions and video for the story to occur in parallel and the pictures and spoken report of the weather to occur in parallel.
