    1616publication. In addition, there are three subclasses of :class:`ExportCIF`:
    1717:class:`ExportProjectCIF`,
    18 :class:`ExportPhaseCIF` and :class:`ExportDataCIF` that
    19 export a project, single phase or data set. Note that ``self.mode`` determines
    20 what is written:
    21 
    22  * `self.mode="simple"` creates a simple CIF with only coordinates
    23    or data, while
    24 
    25  * `self.mode="full"` creates a complete CIF of project.
    26  
     18:class:`ExportPhaseCIF` and :class:`ExportDataCIF` where extra parameters
     19for the _Exporter() determine if a project, single phase or data set are written.
