Yeah, ehrm well... Is this issue closed? Is there a nice solution?
In e.g. XML the basic assumption is that order has meaning, in SQL it is that order has no meaning. Historically (XML coming from a document heritage, SQL from experiments with relational products) this makes sense, but I would prefer it if one could choose wether order is meaningful/worth preserving/relevant or not - instead of being pushed into one way of thinking or another because of the background of the product at hand.
