* Please note that it is not possible to encode Constructive without
* the +infinite_length+ attribute being set to +true+, use
* OpenSSL::ASN1::Sequence or OpenSSL::ASN1::Set in these cases instead.

* === Example - Infinite length OCTET STRING
* partial1 = OpenSSL::ASN1::OctetString.new("\x01")
* partial2 = OpenSSL::ASN1::OctetString.new("\x02")
