Frankly, ozone may be suited for your needs - but not as an XML store. Why do
you want to store your data as XML? Your application is surely based on a great
object model. Why don't you want to "nativly" store those object? XML
introduces space and performance overhead.
ozone provides an API to map objects to XML. There is a default mapping that
maps all kind of objects to XML using a standard Schema which is similar to
KoalaBML. But you may also make your own mapping.
Thus you have both, "native" objects which you application can probably much
easier deal with than XML. And XML for ex/import.
