I know about quirks mode and how it's provoked with <?xml ... ?>. Exactly because of that it has been impossible to use ZPT's XML mode to render web pages -- because IE will choke on the <?xml ... ?> that is necessary to put the ZPT machinery into XML in the first place... a vicious circle so to speak. If we make XML the default mode, I don't see how it would impact IE very much. After all, the <?xml ... ?> processing instruction would then be optional and could be left out for XHTML pages. It would finally be possible to properly embed XForms, SVG etc. into XHTML though.
