One of the key design principles of HTML is that it provides basic
capabilities that allow one to produce usable documents for many 
purposes without having to learn and understand a complex language (the 
amount of copy and paste coding that goes on indicates that even even 
professional web designers can't handle complex language rules).  3-D 
data sets seems to me to be a specialist use, and the other paragraph 
quoted appears to me to require a specialist advertising language.

Rather than trying to bolt on features to support specialist uses, users 
should be first checking to make sure that there isn't a less 
fashionable tool that is designed for the application, and then create a 
language that is optimised for that application.

If you are staying within W3C technologies, I would suggest that this 
would be an SVG application, as I very much doubt that the average 
author of such documents will care about accessibility.

Incidentally, marquee is an accessibility no-no, because it is 
distracting and it is difficult for slow readers (including not native 
language) to read.  That is why it wasn't retained as a presentational 
element in HTML.
