XSD maps xs:list to a C++ sequence container. It is xs:union that spoils
things. In C++/Tree unions are always mapped to a string. Providing a more
elaborate mapping is not trivial and will require full-blown validation to
determine which member type it is.

So if you want a nice list, try to get rid of the union.
