The resulting Gender C++ class will have a dual interface. One of
a type similar to C++ enum and the other of xml_schema::string which 
in turn derives from std::string. So you can initialize a Gender
object using the enum interface and then get the value as a string,
for example:

Gender male (Gender::MALE);
const std::string& male_str = male;
const char* male_c_str = male.c_str ();
