Pipe dreams
The dream of a new web, based on XHTML+SVG+SMIL+XForms, is just that — a dream. It won’t come true no matter how many toy implementations (including Mozilla implementations — we’ve supported XHTML for years) there are. Long before the w3c gets compound documents working on paper (having missed the chance with SVG 1.0 and 1.1, which ambiguate and conflict with CSS), XAML etc. will leak onto the public web.
