java.lang.Objectorg.bouncycastle.asn1.ASN1Object
org.bouncycastle.asn1.cms.Attribute
RFC 5652: Attribute is a pair of OID (as type identifier) + set of values.
Attribute ::= SEQUENCE { attrType OBJECT IDENTIFIER, attrValues SET OF AttributeValue } AttributeValue ::= ANY
General rule on values is that same AttributeValue must not be included multiple times into the set. That is, if the value is a SET OF INTEGERs, then having same value repeated is wrong: (1, 1), but different values is OK: (1, 2). Normally the AttributeValue syntaxes are more complicated than that.
General rule of Attribute usage is that the Attributes
containers
must not have multiple Attribute:s with same attrType (OID) there.
