///  default values, all values are serialized in such a way as to be able
///  to reset values to their defaults for objects that may have already
///  been initialized. When a component serialization service wishes to
///  indicate this to CodeDomSerializer objects, it will place a
///  SerializeAbsoluteContext on the context stack. The member in this
///  context may be null, to indicate that all members are serialized, or
///  a member indicating that only a specific member is being serialized at
///  this time.
