Arg.  Correction:

"we had no SVG-provided examples of the absence of intrinsic ratio"
should have been
" we had no SVG-provided examples of the absence of intrinsic ratio coupled with the absence of size"

In other words, I never found an example (SVG or otherwise) in IE9 that should exercise this rule:
http://www.w3.org/TR/css3-background/#the-background-size

# If both values are ‘auto’ then the intrinsic width and/or height
# of the image should be used, if any. If the image has neither an
# intrinsic width nor an intrinsic height, its size is determined as
# for ‘contain’.

I forgot to mention this linkage in the chain of evaluation ...

http://www.w3.org/TR/SVGMobile12/coords.html#IntrinsicSizing


My recollection is that this explains how the percentages interact with the attachment location.

My other recollection is that, although it's in SVG Tiny 1.2, it was the preferred model and that it was going to be moved or replicated somewhere else in spec land.


Like I said, I'm fuzzy on this area but this combined with the other references led some of us (and definitely me) to the conclusion that we had no SVG-provided examples of the absence of intrinsic ratio during IE9 development.  And none of the new feature set of IE10 has shaken that understanding.
