Section 17 says:

CB_SEQUENCE             | OPT  

It should say:

CB_SEQUENCE             | REQ

Notes:

The section 20.9.3 of CB_SEQUENCE says

"In each CB_COMPOUND request, CB_SEQUENCE MUST appear once and MUST be the
first operation. The error NFS4ERR_SEQUENCE_POS MUST be returned
when CB_SEQUENCE is found in any position in a CB_COMPOUND beyond the
first. If any other operation is in the first position of CB_COMPOUND, NFS4ERR_OP_NOT_IN_SESSION MUST be returned."

Since CB_RECALL_SLOT is REQ operation in NFSv4.1. This make CB_COMPOUND as REQ procedure. Since CB_COMPOUND require CB_SEQUENCE as its first operation and hence CB_SEQUENCE must be required operation.
