Section 3.1 says:

Generic_Headers = (
    ? 1 => int / tstr,  ; algorithm identifier
    ? 2 => [+label],    ; criticality
    ? 3 => tstr / int,  ; content type
    ? 4 => bstr,        ; key identifier
    ? 5 => bstr,        ; IV
    ? 6 => bstr         ; Partial IV
)

It should say:

Generic_Headers = (
    ? 1 => int / tstr,  ; algorithm identifier
    ? 2 => [+label],    ; criticality
    ? 3 => tstr / int,  ; content type
    ? 4 => bstr,        ; key identifier
    ? ( 5 => bstr //    ; IV
        6 => bstr )     ; Partial IV
)

Notes:

Section 3.1 says: "The "Initialization Vector" and "Partial Initialization Vector" header parameters MUST NOT both be present in the same security layer."
