AttributeValue
According to RFC 3280 (http://www.ietf.org/rfc/rfc3280.txt) X.501 AttributeTypeAndValue structure is defined as follows: AttributeTypeAndValue ::= SEQUENCE { type AttributeType, value AttributeValue } AttributeType ::= OBJECT IDENTIFIER AttributeValue ::= ANY DEFINED BY AttributeType ... DirectoryString ::= CHOICE { teletexString TeletexString (SIZE (1..MAX)), printableString PrintableString (SIZE (1..MAX)), universalString UniversalString (SIZE (1..MAX)), utf8String UTF8String (SIZE (1.. MAX)), bmpString BMPString (SIZE (1..MAX)) }
