My retention for the intricacies of SVG sizing is weak, so I usually bug Aaron to double-check myself.


But my loose recollection is that this applies...

http://www.w3.org/TR/SVG/struct.html#SVGElementWidthAttribute

# height = "<length>"
# If the attribute is not specified, the effect is as if a value of '100%' were specified.

And thus the image size is mapped to {100px, <height-of-the-background-positioning-area>} well-before background-size gets evaluated.

<continuing>
... which also means that -- from the perspective of background-size -- the image *does* have both an intrinsic size and an intrinsic aspect ratio.

So I still need an example of the creature that David asked for.
