/**
 * Class Severity is a printing attribute class, an enumeration, that denotes 
 * the severity of a {@link PrinterStateReason PrinterStateReason} attribute. 
 * <P>
 * Instances of Severity do not appear in a Print Service's attribute set 
 * directly. Rather, a {@link PrinterStateReasons PrinterStateReasons}
 * attribute appears in the Print Service's attribute set.
 *  The {@link PrinterStateReasons 
 * PrinterStateReasons} attribute contains zero, one, or more than one {@link 
 * PrinterStateReason PrinterStateReason} objects which pertain to the Print 
 * Service's status, and each {@link PrinterStateReason PrinterStateReason} 
 * object is associated with a Severity level of REPORT (least severe),
 * WARNING, or ERROR (most severe).
 * The printer adds a {@link PrinterStateReason 
 * PrinterStateReason} object to the Print Service's
 * {@link PrinterStateReasons PrinterStateReasons} attribute when the
 * corresponding condition becomes true 
 * of the printer, and the printer removes the {@link PrinterStateReason 
 * PrinterStateReason} object again when the corresponding condition becomes 
 * false, regardless of whether the Print Service's overall
 * {@link PrinterState PrinterState} also changed. 
 * <P>
 * <B>IPP Compatibility:</B> 
 * <code>Severity.toString()</code> returns either "error", "warning", or
 * "report".  The string values returned by  
 * each individual {@link PrinterStateReason} and
 * associated {@link Severity} object's <CODE>toString()</CODE>
 * methods, concatenated together with a hyphen (<CODE>"-"</CODE>) in
 * between, gives the IPP keyword value for a {@link PrinterStateReasons}.
 * The category name returned by <CODE>getName()</CODE> gives the IPP
 * attribute name.
 * <P>
