It's better to rewrite this part to refer to HTML spec, rather than CSS3 UI spec. The property is considered "at risk" in the CSS3 UI spec, and might not be adopted as is in the current spec draft. I found some discussion in CSS WG's meeting notes[2]. As far as I read the CSS3 UI spec, the "auto" value corresponds to the behavior of HTML attribute "tabindex" with its value 0 (cf, the spec is [3] or [4]), which is already implemented in most browsers and the spec is stable.
