To create a presentation, set the type attribute of the main headline to presentation.
Each of the sub-heads contains the title of one of the slides. The second-level heads form the content of each slide.
You can also change the theme and transition values for the presentation by adding attributes to the main headline. The possible values for theme are sky, beige, simple and default. And for transition: cube, page, concave, linear, default.
Example 10 illustrates.
