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.

MM
Style sheets are only one target, and 4.4 is not strictly a technique of
1.5. 4.4 itself does have implications with other technologies which
overloading 1.5 will not solve. In fact, if you look at the 1.0 to 2.0
checkpoint mapping[1], noting that 4.4 was roughly analogous to 1.7 in the
January draft, eight 1.0 checkpoints now hang off of 4.4. It inherits more
checkpoints than any other in 2.0.

While CSS is strictly a presentation technology (and we urge people not to
use it to convey content), other technologies such as scripting can convey
content or provide essential portions of the page that can make the site
unusable. One can comply with 1.5 and still fail 4.4.

AP
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.
[...]
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?

MM
Pages designed with HTML+CSS _should_ be usable without CSS available or
turned on. That was the whole point of the technology. In WCAG 1, Checkpoint
6.1 (which 4.4 subsumes) says "Organize documents so they may be read
without style sheets. For example, when an HTML document is rendered without
associated style sheets, it must still be possible to read the document.
[Priority 1]"
