Original Text
-------------
   Here the parameters are present and contain the default parameters,
   i.e., hashAlgorithm of SHA-1, maskGenAlgorithm of mgf1SHA1,
   saltLength of 20, and trailerField of 1.

Corrected Text
--------------
   If the default parameters are used, i.e., hashAlgorithm of SHA-1, 
   maskGenAlgorithm of mgf1SHA1, saltLength of 20, and trailerField 
   of 1, the parameters MUST NOT be encoded according to the 
   Distiguished Encoding Rules (DER) of ASN.1. Therefore the encoding
   is the same as of A.4.1.

   0000 : SEQUENCE
   0002 :   OBJECT IDENTIFIER  RSASSA-PSS (1.2.840.113549.1.1.10)
   000d :   SEQUENCE

   Name = RSASSA-PSS with default parameters,
          oid = 1.2.840.113549.1.1.10
   Length = 15
   0000: 300d 0609 2a86 4886 f70d 0101 0a30 00

Notes
-----
Section 3 requires the use of DER:
The ASN.1 used here is the same ASN.1 used in the AlgorithmIdentifier of PKIX (see Section 4.1.1.2 of [RFC5280]), encoded using distinguished encoding rules (DER) [CCITT.X690.2002].
