Java is different from C++ so it shouldn't be surprising that the
XML Schema mappings are different as well. For example for an 
element with maxOccurs="unbounded" JAXB would return a type-less
java.util.List. This is not how it is done in C++. In XSD we return
a statically-typed container template. To make this convenient to
use we provide a typedef for this container along with accessor
and modifier functions which, on the surface, may seem more
complicated that JABX (your code will be a lot cleaner and safer
without the the type casts, though).

Overall, we tried to make the mapping as simple to use as possible
while being able to handle non-trivial, real-world schemas. We don't
have a simpler mapping for you. Therefore you have two options:

1. Look if someone else offers a mapping that satisfies your 
   requirements.

2. Get to understand why things are done the way they are done
   in XSD. To get started, I suggest that you read through the
   C++/Tree Mapping Getting Started Guide:

   If you are in a hurry, at least read chapters 2 ("Hello World Example")
   and 4 ("Working with Object Models").
