Re: [css3] "keep aspect ratio" feature

The idea is interesting, but by redefining what "auto" width or height  
mean in the presense of an explicit ratio, don't you proclude the  
ability to have a flexible width with a height that is proportional to  
that width? Or does the new meaning of "auto" only apply to height?
