* also the first step in report generation after DE loads the report in.
 * 
 * <p>
 * special consideration in styles
 * <p>
 * BIRT uses a simlar style mode with CSS, but not exactly the same. The main
 * differences are:
 * <li> text-decoration is not inheraible which simplify the CSS standard. This
 * rules makes text-decroation are usless for all the containers. As the HTML
 * treat the text-decoration inheritable in block-level element, the ENGINE must
 * remove the text-decoration from the container's styles.
 * <li> BIRT doesn't define the body style, it uses a predefined style "report"
 * as the default style.
