Why not a conditional requirement along the lines of, "If a UA is allow 
interactivity and access to the source of a document, it must provide 
access to a full DOM serialization of the document, and may provide 
access to the raw document (pre-parsing)."  Not suggesting that actual 
wording, of course, just the general intent.

That's always the case, but that's nevertheless the goal of 
specifying... to achieve broad interoperability.  We can't guarantee 
anything, including the parsing algorithm, but it's in the best interest 
of the UA to be match the spec (hopefully).
