[Rating] Presentation

I'd like to achieve the following

when CSS is not supported/used, we get: [Required] with brackets.
if it is, then 'Required' to be in white/red, but without brackets.
(same kind of things with Recommended, New and Interim)

This is possible, using the following markup:

<SPAN class=bracket>[</SPAN>
<span class="man">Required</SPAN>
<SPAN class=bracket>]</SPAN>

and CSS statements:

span.man { 
       color : white;
       background : red;
}
span.bracket {
       display: none ;
}


Also, right now, Required and Recommended are marked with SPAN, but
not New and Interim. I suggest adding SPAN there as well, with bracket
class and a style that creates a box around rather than a color.

A la:
  span.new, span.interim { border-width: 1 ; }

(Took me 5 minutes to do with an emacs macro, I also got rid of all
the &nbsp; and some font properties that looked bad for me in this
page)
