/** Writes out RDF in the abbreviated syntax,  for human consumption 
   not only machine readable.
 * It is not normal to call the constructor directly, but to use
 * the method RDFWriterF.getWriter("RDF/XML-ABBREV").
 * Does not support the <code>NSPREFIXPROPBASE</code> system properties.
 * Use <code>setNsPrefix</code>.
 * For best results it is necessary to set the property 
   <code>"prettyTypes"</code>. See setProperty for information.
