	That is in fact correct. The way to think of what you need to ram into
an any's _value is (perhaps) this:

	"I want to pass a pointer to a struct element"

	This is because everything is recursively marshalled, and it makes
struct/union/sequence/array marshalling trivial. 

	Thus in a struct we have:

struct {
	CORBA_long   a;
	CORBA_Object b;
	CORBA_double c;
	CORBA_any    d;
	CORBA_char  *e;
};

	Thus we need _value to be either a CORBA_long *, a CORBA_Object *, a
CORBA_double *, a CORBA_any * or a CORBA_char _**_ :-)

	HTH - and good work,

	Regards,

		Michael.
