The following version of the above is legal IDL.

  typedef long bar;
  struct foo {
    bar f1;
    struct boo {
      short s;
    } f2;
  };

A CORBA struct can contain any type declaration apart from a typedef 
as the type of a member.  But it is probably a bad idea to nest 
declarations inside structs >>unless<< you are defining a recursive 
data type.

I suggest you invest in a good textbook on CORBA.
