The SCU may erase the text string by setting a zero length value in the Attribute Text String (2030,0020).

The SCP shall set new values for the specified Attributes of the specified SOP Instance.

The SCP shall return the status code of the requested SOP Instance update. The meaning of success, warning, and failure status codes is defined in Section H.2.5.
