Code review comment for lp://qastaging/~justin-fathomdb/nova/output-xml-in-order

In JavaLand, this is essentially the standard technique now (and it is
really great). I think it's the same in RubyVille. Hopefully this
will make it into Python as a core library sometime soon, so you won't
have to maintain it.

Until that happens, I think the best thing to do here is to agree to
disagree :-) I don't think it's necessarily relevant to the merge
proposals?
