3.2.5.1.2 Processing an Application-Removed PDU

The receiver of an Application-Removed PDU (OD_APP_REMOVED) MUST first validate the common header for consistency (section 3.1.5.1). If the PDU size is not long enough to contain all the fields in the message, the connection SHOULD be terminated.<11>

If the receiver wants to use the application and window list facilities of this protocol, it SHOULD process the information according to section 3.1.5.3.
