9 Receiver-Immutable Fields

A number of elements/attributes must be immutable, i.e., after the object is created the fields cannot be changed. If a receiver (i.e., client, consumer, or customer) tries to change an immutable item, the sender (i.e., server, producer or store) must send an EPERMISSION_DENIED error.
