C++/Tree and C++/Hybrid are similar in the sense that they both represent
XML as an in-memory, tree-like object model. The implementations of the
mappings, however, are quite different. In particular, C++/Hybrid is
more minimal since it is targeted at mobile/embedded/light-weight
applications. So if you have some code that uses C++/Tree simply
recompiling the schemas will not work. You will need to do some
porting work. Though, since the programming models are similar, this
shouldn't be too difficult.

Right, there are quite a few "extras" provided by C++/Tree (comparison
operators, ostream operators, DOM association, XPath) that are not
present in C++/Hybrid.
