In an offline note, Franklin Tse asked about the empty string value for the bidi attribute. He had raised an issue before about whether that could be dropped, which I had originally decided to go ahead and do. However, after going through a number of aggregated feed scenarios, having the ability to explicitly state that no default direction had been specified seemed to be more important than relying on a default direction of LTR. I can definitely be convinced otherwise, of course.
