    Such filters can be used for exporting a content.

        <type>XExporter</type> which is supported by this service too.

        <p>
        Tip:<br>
        If same implementation provides the service <type>ImportFilter</type> too,
        code must distinguish between filtering from a source document (for export) or
        filtering to a target document (for import). This can be recognized by saving
        state of used interfaces <type>XExporter</type> or <type>XImporter</type>!
        Otherwise it's not clear which action is required here.

        If filter supports this optional interface, he will be initialized by the factory directly
        after creation. The factory will pass follow informations to this new instance:

        to get further informations about it (e.g. his registration for mime types or extensions etc.)
        It's important that returned string is the "internal name" of the filter which must be
        unambigous against all other registered filter in current instalation.

        Supported method setName() sould be ignored or forwarded to the FilterFactory.

        from real implementation of the FilterFactory if it will be allowed or not!
