               <member>XImplementationLoader::writeRegistryInfo</member>
               writes a list of implementation names hosted by this component.
        @param implementationLoaderUrl specification bug, ignore this parameter, please
               pass an empty string.
        @param locationUrl Points to the location of the file containing
               the component (for instance a .jar-file or a shared library).
               This parameter
               should be in an URL format (= protocol:protocol-dependent-part).
               In case the string contains no
               leading "protocol:", the implementation in general assumes,
               that it is a relative file url. <p>Special loaders may define
               their own protocol (for instance an executable loader may need

        @param xKey A registry which may be used to read static data previously
               written via <method>XImplementationLoader::writeRegistryInfo()</method>.
               The use of this parameter is deprecated.
               
        @return returns a factory interface, which allows to create an instance of
                the concrete implementation. In general, the object supports a
                <type scope="com::sun::star::lang">XSingleComponentFactory</type>
                and the <type scope="com::sun::star::lang">XServiceInfo</type> interface. The
                XServiceInfo interface informs about the capabilities of the
                service implementation, not the factory itself.
