Yes, I am satisfied with it. Do note that Ian took a fairly radical approach, removing various prose requirements (e.g. that <br> should act as a bidi paragraph break) in favor of a blanket requirement that the default style sheet be followed, with cross-references to where the default style sheet has bidi implications. I think it is ok, but others on the i18n WG might want to give this some thought.
