* A Doxia Sink that produces an aggregated FO model. The usage is similar to the following:

*
* FoAggregateSink sink = new FoAggregateSink( writer );
* sink.setDocumentModel( documentModel );
* sink.beginDocument();
* sink.coverPage();
* sink.toc();
* ...
* sink.endDocument();

* Note: the documentModel object contains several
* document metadata, but only a few
* of them are used in this sink (i.e. author, confidential, date and title), the others are ignored.
