I don't think you can do anything about this in your current setup.
You could get rid of the base and use element groups instead. Not very
OO but will work. Another alternative would be to use substitution
groups (i.e., in the base have a single abstract element which is
extended as sprite, graphics, etc). One advantage of this approach
is that you will be able to determine order of elements in C++/Tree.
The disadvantage is that it will result in a schema that is a bit
looser than what you want.
