Ian Hickson, the editor of the HTML 5 specification, said on the WHAT WG mailing list just recently: “I have in fact already begun looking at exactly what the parsing and semantic requirements for will have to be. It should be added to the spec in the coming weeks.” Currently the only browser that natively supports ruby is Internet Explorer, at least somewhat. This should be great news for Microsoft. For once they will actually have a lead compared to Gecko based browsers, Opera, Konqueror or Safari in supporting a part of the HTML 5 spec.
