Section 5.1 says:

The ASN.1 at the bottom of page 11 says:

        SIM ::= SEQUENCE {
            hashAlg          AlgorithmIdentifier,
            authorityRandom  OCTET STRING,   -- RA-chosen random number
                                             -- used in computation of
                                             -- pEPSI
|           pEPSI            OCTET STRING    -- hash of HashContent
                                             -- with algorithm hashAlg
        }

It should say:

        SIM ::= SEQUENCE {
            hashAlg          AlgorithmIdentifier,
            authorityRandom  OCTET STRING,   -- RA-chosen random number
                                             -- used in computation of
                                             -- pEPSI
|           pEPSI            OCTET STRING    -- hash of hash of
|                                            -- HashContent with
                                             -- algorithm hashAlg
        }

It should say:

See above.

Notes:

Rationale:
PEPSI is an iterated hash; see Section 4.4 where the last
line on page 9 says,
where PEPSI = H(H(P || R || SIItype || SII))
-----------------v-------
and Section 5.2 for the definition of HashContent.
