Re: responsive images

Right. I didn't saw the draft but it would only work for non-informational images (for design only). 
Then the first two options are still open:
- responsive images within HTML (not CSS).

But then we should change list. This topic will appear shortly in html list, too, when it's approved.

I believe the intent of this is to specify a declarative syntax for referencing an image, the path alias technique I suggested just has the added advantage of being useful in any other place as well. -ck
