This test doesn't check that original document no longer has a doctype after createDocument. However, this is indeed what happens in Firefox in my testing.

I guess it depends on the level of one's familiarity with the API. To me, having DOM modified when document's doctype is used as an argument in createDocument call is surprising - the form of this call doesn't suggest that original document is modified.

What does IE do? Perhaps we have an opportunity to actually improve the Web here, and not just mimic a Gecko quirk.
