// Update the new attribute values. If this is being called
// then this object is either a remote object that was
// discovered or it has some attributes that are owned by
// another federate.

// Note: This version does not implement any ownership
// transfer - the above was a generic statement.
//
// RETURN VALUES:
// None.
//
// HISTORY:
// 1) Created 11/6/96
// 2) Updated to RTI 1.3 3/26/98
