/**
 * Exports a JasperReports document to DOCX format. It has binary output type and exports the document to a
 * grid-based layout, therefore having the known limitations of grid exporters.
 * <p/>
 * It can work in batch mode and supports all types of
 * exporter input and output, content filtering, and font mappings.
 * <p/>
 * Currently, there are the following special configurations that can be made to a DOCX
 * exporter instance (see {@link net.sf.jasperreports.export.DocxReportConfiguration}):
 * <ul>
 * <li>Forcing the use of nested tables to render the content of frame elements using either
 * the {@link net.sf.jasperreports.export.DocxReportConfiguration#isFramesAsNestedTables() isFramesAsNestedTables()} 
 * exporter configuration flag or its corresponding exporter hint called
 * {@link net.sf.jasperreports.export.DocxReportConfiguration#PROPERTY_FRAMES_AS_NESTED_TABLES net.sf.jasperreports.export.docx.frames.as.nested.tables}.</li>
 * <li>Allowing table rows to adjust their height if more text is typed into their cells using
 * the Word editor. This is controlled using either the
 * {@link net.sf.jasperreports.export.DocxReportConfiguration#isFlexibleRowHeight() isFlexibleRowHeight()} 
 * exporter configuration flag, or its corresponding exporter hint called
 * {@link net.sf.jasperreports.export.DocxReportConfiguration#PROPERTY_FLEXIBLE_ROW_HEIGHT net.sf.jasperreports.export.docx.flexible.row.height}.</li>
 * <li>Ignoring hyperlinks in generated documents if they are not intended for the DOCX output format. This can be 
 * customized using either the 
 * {@link net.sf.jasperreports.export.DocxReportConfiguration#isIgnoreHyperlink() isIgnoreHyperlink()} 
 * exporter configuration flag, or its corresponding exporter hint called
 * {@link net.sf.jasperreports.export.DocxReportConfiguration#PROPERTY_IGNORE_HYPERLINK net.sf.jasperreports.export.docx.ignore.hyperlink}</li>
 * </ul>
