Not really. Again XSD is simply another way to define the desired output
structure. It does not understand the DB representation of the data
therefore you still have the need to define how to transform the DB data to
the desired XML structure. There is no magic way take a DB schema and a XSD
to have some process automatically know how to map one to another.
