def get_authority(self):
return self._my_map['<STR_LIT>']<EOL>
Gets the authority of this ``Type``.

        The authority is a string used to ensure the uniqueness of this
        ``Type`` when using a non- federated identifier space.
        Generally, it is a domain name identifying the party responsible
        for this ``Type``. This method is used to compare one ``Type``
        to another.

        return: (string) - the authority of this ``Type``
        *compliance: mandatory -- This method must be implemented.*
