                                  whether this value is available. Defaults
                                  to True.
                       derived:   Specifies python code to apply to other
                                  fields of the parent structure to derive the
                                  value of this field. Defaults to None.

                                  in labeled output. Defaults to True.
                       label:     The label for this field. If unspecified, the
                                  label will be derived from the field name.
                       length:    if > 1, indicates this field is an array of
                                  the specified cType, otherwise is is a
