I should think that depends on the database. In any case, I didn't intend to suggest that the classic architecture would become obsolete, but merely to agree that Andrew was onto something that could be very useful. For large-scale queries over aggregated data, the classic mapping of single document to single result via a single transform may not serve so well. This is where XQuery comes in. But XQuery alone is a blunt instrument for final transformations for rendering, which you are also likely to want.

If you use a small main Source XML with the minimum necessary instructions for a transform, then you can bring in the bulk the required XML through the document function (maybe with a URIResolver that uses XQuery, but...)
Isn't this effectively the same thing?
Don't the XML databases work best with many small documents rather than one or a few very large documents?
