/**
 * Class JobStateReason is a printing attribute class, an enumeration, that 
 * provides additional information about the job's current state, i.e., 
 * information that augments the value of the job's {@link JobState JobState} 
 * attribute. Class JobStateReason defines standard job state reason values. A 
 * Print Service implementation only needs to report those job state 
 * reasons which are appropriate for the particular implementation; it does not 
 * have to report every defined job state reason. 
 * <P>
 * Instances of JobStateReason do not appear in a Print Job's attribute set 
 * directly. Rather, a {@link JobStateReasons JobStateReasons} attribute appears 
 * in the Print Job's attribute set. The {@link JobStateReasons JobStateReasons} 
 * attribute contains zero, one, or more than one JobStateReason objects which 
 * pertain to the Print Job's status. The printer adds a JobStateReason object 
 * to the Print Job's {@link JobStateReasons JobStateReasons} attribute when the 
 * corresponding condition becomes true of the Print Job, and the printer 
 * removes the JobStateReason object again when the corresponding condition 
 * becomes false, regardless of whether the Print Job's overall {@link JobState 
 * JobState} also changed. 
 * <P>
 * <B>IPP Compatibility:</B> The category name returned by 
 * <CODE>getName()</CODE> is the IPP attribute name.  The enumeration's 
 * integer value is the IPP enum value.  The <code>toString()</code> method 
 * returns the IPP string representation of the attribute value.
 * <P>
