This depends on the definition of "database". In many cases, you don't 
really even need read-write capabilities... just the ability to 
instantiate a DOM tree when you need to combined with the ability to 
rapidly navigate to arbitrary nodes in the tree (i.e. a random-access 
DOM). There are any number of ways of providing that, and in almost all 
cases I would not call the result a "database" as such. For that 
matter, I'm not sure that XQuery makes all that much sense in many of 
those cases either.
