These operations can do anything you like. Attributes are just
syntactic sugar for:

interface Obj1 {
  string get_name();
  void   set_name(in string s);
};

In the trivial case where there is a string member variable in the
object implementation, you can just define the operations to set and
return the member string. You must be careful to get your memory
management right, and call CORBA::string_dup() at the correct times.
