Excuse me for being still very confused what is intended by 4.4 ... but I 
had thought it was referring to technologies that support multimedia and 
special effects, svg, etc. Now, I see, the target is the style sheets.

But the problem of styles sheets arises because of
1.5 Separate content and structure from presentation.

where designers are told to use styles sheets, then in 4.4 if they have 
decided to follow 1.5, they then have to turn around and make the site 
useful for those who don't use style sheets. Would it be easier to write if 
this were moved from a standing checkpoint to being a how-to in 1.5? The 
two seem related, and it seems likely to me that other readers of the 
document may overlook the connection of 1.5 and 4.4.

  Does 4.4 mean that if you design the markup of a page in CSS you must 
also duplicate it in HTML, providing markup for both html and for css? If 
so, shouldn't it be a technique on how to accomplish 1.5 properly?

If we continue with both checkpoints, perhaps we should have cross links 
between the two so the audience can connect between them.
