Clearly the internal storage format for XML document is (as you have identified) quite hard to get right, balancing the requirements of update performance, retrieval performance, and space efficiency. It's therefore a source of competitive advantage, so suppliers therefore aren't going to be very open about how they tackle the problem. In principle, of course, as a user you shouldn't need to know how the data is stored internally.
