Forgive for mingling here, but I'd like to know what you (or others) think of, for example, this: h1 {font-size: medium; font-weight: normal;} i {font-style: normal;} Doesn't this prove that the parts of CSS that are required for a conforming CSS UA can be used to create a non-conforming presentation of an HTML document? [1] I haven't studied XBL at all, and I'm suspicious of efforts to mix behavior and content and presentation. But I'm even more suspicious of efforts that promote sending generic XML over the net for general purpose documents. If a document *needs* CSS and/or XBL and/or XSTL to be supported by the UA before it is usable in that UA in any way, than it has failed to be a good WWW document. If such documents become widespread, it would be less likely that a competetive market of user agents survives. [1] Ian posed a related question already by the time I got around to sending this message, but what the heck, lets make this thread even longer. -- Rijk van Geijtenbeek
