This approach is fine with me. Since border-styles are also part of the same spec, can we also tighten that up too? There is no inter-op currently on dot shape or spacing, so standardizing that would be unlikely to break anything substantially. For "dotted", it does now say "round" dots, and I think we can be more precise. Something along the lines of this:

‘dotted’
A series of round dots, evenly spaced around the entire border (including corners and border radii). The space between dots should be approximately equal to the width of one dot, but this spacing should be adjusted in order to achieve uniform spacing, with no less than .75 dot-width of space between dots. Spacing of dots may be different along vertical border sides than along horizontal border sides, in order to achieve symmetry at the corners.


Webkit is still non-complient with the "round" dot requirement, and Gecko doesn't make the corner dots round. Here was the results of a test I did a while ago, with little or no improvement noticeable since:
