ASN.1 values of type BIT STRING are mapped to Go variables of type asn1.BitString. The ASN.1 values may be defined using binary strings, hexadecimal strings, or using sets of named bits:

ASN.1 production:

   <name> BIT STRING ::= '<bstring>'B

Generated code :

   var Asn1v<name> asn1.BitString = asn1.BitString{ BitLength: <len>, Bytes: []byte{<data>}}

where <len> would be the length in bits and <data> would be a comma-separated list of hexadeciaml byte constants.
