--------------------------------------
Type: Technical
Reported by: Sushil Agarwal <sushil89@yahoo.com>

Section: 17

Original Text
-------------
CB_SEQUENCE             | OPT  

Corrected Text
--------------
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.
