Your proposal doesn't say what you'd do for XHTML5. aaa:aria-* isn't  
good for XHTML5, because it would create a scripting (and browser  
code path) discrepancy between HTML5 and XHTML5. If XHTML5 used aria- 
*, using aaa:aria-* for SVG would leave a scripting and browser code  
path discrepancy between XHTML5 and SVG.

I think it isn't pretty, because aaa:aria-* has two prefixes, which  
is crufty. It isn't easy to use or intuitive, because the syntax and  
DOM differ between host languages.
