Imports
java.util.Enumeration, org.bouncycastle.asn1.ASN1EncodableVector, .ASN1Integer, .ASN1Object, .ASN1ObjectIdentifier, .ASN1Primitive, .ASN1Sequence, .ASN1Set, .ASN1TaggedObject, .BERSequence, .BERSet, .BERTaggedObject, .DERTaggedObject, .DLSequence
RFC 5652:

A signed data object containing multitude of SignerInfos. 

SignedData ::= SEQUENCE {
    version CMSVersion,
    digestAlgorithms DigestAlgorithmIdentifiers,
    encapContentInfo EncapsulatedContentInfo,
    certificates [0] IMPLICIT CertificateSet OPTIONAL,
    crls [1] IMPLICIT CertificateRevocationLists OPTIONAL,
    signerInfos SignerInfos
  }

DigestAlgorithmIdentifiers ::= SET OF DigestAlgorithmIdentifier

SignerInfos ::= SET OF SignerInfo

The version calculation uses following ruleset from RFC 5652 section 5.1: 

IF ((certificates is present) AND
   (any certificates with a type of other are present)) OR
   ((crls is present) AND
   (any crls with a type of other are present))
THEN version MUST be 5
ELSE
   IF (certificates is present) AND
      (any version 2 attribute certificates are present)
   THEN version MUST be 4
   ELSE
      IF ((certificates is present) AND
         (any version 1 attribute certificates are present)) OR
         (any SignerInfo structures are version 3) OR
         (encapContentInfo eContentType is other than id-data)
      THEN version MUST be 3
      ELSE version MUST be 1
