/**
 * 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>
