I have tried that code with the latest Firefox 1.5 beta nightly 
(Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b5) 
Gecko/20050924 Firefox/1.4) and I don't get any errors and the code 
works as expected in my view.
There was a bug with E4X literals Brendan has mentioned in an older 
thread so you might have run into that bug. Try a newer build, I think 
the problem is fixed and the above should work now.

The E4X object model does not know DOCTYPE declarations at all, an XML 
object represents an element or an attribute or a comment or a 
processing instruction or a text node. And a DOCTYPE declaration is not 
a processing instruction.

So you can't have a literal/an initializer with a DOCTYPE declaration.
