According to the XML spec, attribute order is irrelevant [1]

    "Note that the order of attribute specifications in
     a start-tag or empty-element tag is not significant."

Now one could argue that we might want to be stricter in the
XML->SXML processor, which would be fine, but OTOH there's a
price to pay. The question is whether we want to go there --
just imagine another XML processor in the middle changing
attribute order. It would be spec compliant. What now?

Tough question.
