 * must fulfill two conditions:
 *
 * 1) provide a translation from the API event names to XML event
 * names 
 * 2) Register XMLEventExportHandler instances for all script types
 * that you would like to export.
 *
 * The Export()-Methods all have a bUseWhitespace parameter that
 * causes the exported elements to be surrounded by whitespace, which
 * in turn causes the elements to be indented properly. By default,
 * whitespace is used, but it may not be called for in all cases (e.g
 * events attached to hyperlink within a paragraph.)
