Some quick comments on some of the comments regarding the tests:

How does one distinguish a document returned with parse error information 
from one that happens to look like a parse error but was well-formed?

I wouldn't mind including more information but it seems like it should be 
out-of-band.

If a site is expecting an exception and gets null, then they'll get an 
exception when they try to dereferene the null, so in most cases it seems 
like this would work anyway.

I think it's important that we test that the DOM returned from XHR is DOM 
Core conformant just like any other, so this seems like an important and 
relevant testing area for XHR.
