Huh, what is a "meaningful presentation" exactly? To me, what is  
meaningful content is *not* presentational. The presentation is the  
way you arrange and surround your content to make it attractive (or  
not). Your definition of SVG as "presentational" precludes it from  
being meaningful, although you specifically say it can be meaningful  
too so I'm a little confused.

SVG is simply an image description markup language, just like HTML is  
a document description markup language. SVG being presentational  
depends on how it is used. SVG may be suitable for visual media  
mostly, that doesn't automatically make it presentational.

And just like HTML, you can, to a degree, separate the meaningful  
parts from the presentational parts in an SVG image: if a color was  
chosen for presentational reasons, set it using CSS; if the chosen  
font for a block of text is not meaningful to the document, set it  
with CSS or just inherit it from the HTML document if you have inline  
SVG.
