You can already get XML+javascript into the browser, using 
the "document reboot" trick, which is to say, add an XSLT stylesheet PI 
to your XML that transforms it into an HTML shell document (with 
embedded onload() javascript elements) that contains your entire 
original document as an "XML data island". This works perfectly well 
in firefox, opera, chrome and safari. Konqueror 4.3.5 and IE 8 (MSXML3), 
of course, cock it right up :-/ 
Konqueror doesn't even attempt to handle the PI and IE mis-interprets 
any XML namespace <title> elements as html title elements. Allegedly 
using javascript in IE it is possible to choose the version of MSXML 
you want to use, but unfortunately the damage is already done by the 
default MSXML3 before any javascript is loaded.
