Thanks ! Now that you've clarified it, I think I recall a f2f discussion
about this. In my mind though, "at least one" does not exclude "both". May
I suggest this be clarified with explicit prose ? E.g.
Update:
#If two values are given and at least one value is not a keyword, then the first value represents the horizontal position #(or offset) and the second represents the vertical position (or offset). <percentage> and <length> values here represent an #offset of the top left corner of the background image from the top left corner of the background positioning area.
...to:
#If two values are given and one value is not a keyword, then the first value represents the horizontal position #(or #offset) and the second represents the vertical position (or offset). <percentage> and <length> values here represent an #offset of the top left corner of the background image from the top left corner of the background positioning area. If both
#values are keywords, the vertical and horizontal component can be specified in either order.
