Yes, C++/Tree and C++/Hybrid use different approaches to mapping
compositors to C++. C++/Tree flattens the structure which results
in simpler to use API but looses ordering information in some
cases. C++/Hybrid recreates the compositor structure precisely
which can lead to a fairly complex API for complex content models.
This earlier email has more information on this:

We are also thinking of adding some extra mechanism to C++/Tree to
allow preserving/specifying the element order for certain types.
Let me know if you are interested in hearing what we have so far
and maybe provide some feedback.
