/**
 * Class JobSheets is a printing attribute class, an enumeration, that
 * determines which job start and end sheets, if any, must be printed with a
 * job. Class JobSheets declares keywords for standard job sheets values.
 * Implementation- or site-defined names for a job sheets attribute may also be
 * created by defining a subclass of class JobSheets.
 * <P>
 * The effect of a JobSheets attribute on multidoc print jobs (jobs with
 * multiple documents) may be affected by the {@link MultipleDocumentHandling
 * MultipleDocumentHandling} job attribute, depending on the meaning of the
 * particular JobSheets value.
 * <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. For a subclass, the attribute value must be
 * localized to give the IPP name and natural language values.
 * <P>
