I should restate, it is possible but it is may be too slow to be practical. Too slow compared to the results people get when using rdb as "intended" meaning different tables for different things and not generalizing data into a few tables.

When your "generic modelling" design is nearly complete (meaning theorectically able to model any data/structure possible) you will mostly need to resolve many more relationships than currently.

Also in a rdb, the time to resolve relationship increases with the number of records. In XDb, the time to resolve a relationship is constant regardless of the number of objects (as long as they fit in memory) and is approximately 1/100 millionth of a second on a 800 Mhz PC.
