2) attribute aliasing support
- x509CertificateIssuer
- x509CertificateSerial
- x509CertificateIssuerAndIssuer
3) AuthorityKeyIdentifier support(one of certificate extension)
4) Misc. improvement
- integrate OID and its decoder mapping table
- normalize and validate the values of both component asserions and
extracted components
5) Misc. bug fix
holds a single attribute type 'componentTest'. Fix
up test031 to avoid modification of standard schema.
(Not sure why this attribute is needed, tests likely
should operate on userCertificate and other existing
attributes which complex syntaxes.)
