The problem with your code is that you are for some reason assuming
that `user` would be dropped for some reason: it is not. JSON
structure that would be equivalent is rather:
{ "user" : {
"name" : "Joe",
"age" : 28
}
}
So basically there is no 'age' property in main level object: there is
just 'user'. This is by design; while there is no guarantee Tree model
api works (it is not officially supported by XML backend), it will try
to represent XML content as closely as possible.
The only way to do that is to retain root element name as well.
