describes an export filter for XML-based file formats.
First, the XExportFilter::exporter method must be
called to provide the export component with the target location to
which the data should be exported. Then, the source document's XML
representation will be generated by calling the appropriate methods
of the ::com::sun::star::xml::sax::XDocumentHandler
interface. Error conditions must be signalled by throwing
a ::com::sun::star::xml::sax::SAXException in the
::com::sun::star::xml::sax::XDocumentHandler calls.
