What's an "HTML document" in your opinion? Neither the network byte  
stream nor the object implementing the Document DOM interface go away  
and get replaced. There is exactly one sequence of characters that  
gets examined by the tokenizer. There might have been a different  
sequence of characters if scripting had been turned off, but that  
sequence was never examined by the tokenizer.

What's the old document? What's the new one?

How is the current spec not sufficiently describing the relationship  
of document.write and the parser state machine? Describing document  
transitions as a state machine doesn't make sense here, because  
there's no state machine-like transition (see above).
