   To take a distinguished name, and generate a name of this format with

    1.  If the first attribute is of type CommonName, the type may be

    2.  If the last attribute is of type Country, the type may be
        omitted.

    3.  If the last attribute is of type Country, the last

    4.  All attributes of type OrganisationalUnit may have the type
        omitted, unless they are after an Organisation attribute or
        the first attribute is of type OrganisationalUnit.
