	 * @image html sample-postnet.svg "Sample USPS POSTNET Barcode"
	 *
	 *
	 * ### Input Data Format ###
	 * 
	 * The *POSTNET* specification defines 10 characters, consisting solely
	 * of decimal digits (0-9).  The BarcodePostnet validator and encoder will
	 * ignore spaces and dashes (-).  The validator will only accept input
	 * data with 5 digits (ZIP), 9 digits (ZIP+4) or 11 digits (ZIP+4+DC).
	 *
	 *
	 * ### Checksum Property ###
	 *
	 * The *checksum* property is ignored.  A mandatory check digit will
	 * always be automatically generated and appended to the input data
	 * prior to encoding.
	 * 
	 *
	 * ### Show Text Property ###
	 *
	 * The *Show Text* property is ignored.
	 *
	 *
