ASN.1 type DigestAlgorithmIdentifiers is defined as follows:

    DigestAlgorithmIdentifiers ::= SET SIZE(0..MAX) OF DigestAlgorithmIdentifier

Type DigestAlgorithmIdentifiers references the following type:

    DigestAlgorithmIdentifier ::= SEQUENCE {
       algorithm   ALGORITHM.&id({DigestAlgorithms}),
       parameters  ALGORITHM.&Type({DigestAlgorithms}{@algorithm})  OPTIONAL
    }
