21: * which a DOM author could effect immediate change to the style of an
22: * element without modifying the explicitly linked style sheets of a
23: * document or the inline style of elements in the style sheets. This style
24: * sheet comes after the author style sheet in the cascade algorithm and is
25: * called override style sheet. The override style sheet takes precedence
26: * over author style sheets. An "!important" declaration still takes
27: * precedence over a normal declaration. Override, author, and user style
28: * sheets all may contain "!important" declarations. User "!important" rules
29: * take precedence over both override and author "!important" rules, and
30: * override "!important" rules take precedence over author "!important"
31: * rules.
32: * <p> The expectation is that an instance of the <code>DocumentCSS</code>
33: * interface can be obtained by using binding-specific casting methods on an
34: * instance of the <code>Document</code> interface.
