I reviewed CSS3 Image Values and found no major issues. I did find some minor or editorial issues. Here is the first:

Under 3.3 element(), in the sections labelled "Otherwise":

| The function represents an image with width and height equal to the | bounding box of the referenced element.

[plus several more mentions of "bounding box"]

"Bounding box" is not defined in this spec or in CSS 2.1. In other contexts, the term "bounding box" often refers to the total painted area for an element, including shadows and overflow. I suspect "border box" is what is meant, since shadows and some border images are excluded.

Yes, I did indeed mean "border box". Fixed and logged as issue 3.

I've subsequently changed this usage over to "decorated bounding box", and defined what that means for CSS and SVG: <http://dev.w3.org/csswg/css3-images/#decorated-bounding-box>

Is this an acceptable definition?

Super awesome, as T-Rex would put it.
