You have to cast it. XML data models generally require huge amounts of
dynamic casting to implement within an OO language.

With the new libraries you can also examine the elementQName or schemaType
properties to derive guesses as to what type of object it might be, but in
Java a dynamic cast is much faster than that. In C++, it's rather similar.
