Gosh, I would still hope we do data modeling: it's part of data analysis. Once you have it at a conceptual level, you still need to physically represent it. Although that may be more intuitive (to us) in an XML containment hierarchy than it would be in a set of relational tables strung together with joins, there's still more than one way to skin a conceptual cat, even in XML. Same goes for performance tuning. If you don't have the right properties collocated in the elements, you're going to have a lot unnecessary document navigation to do. Again, I don't pretend to imagine that doing it right in XML is as hard as doing it right in an RDBMS, but easiest of all is doing it wrong in ways multifarious.
