/**
 * Class {@code 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 {@code 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 {@code JobSheets}.
 * <p>
 * The effect of a {@code 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 {@code JobSheets} value.
 * <p>
 * <b>IPP Compatibility:</b> The category name returned by {@code getName()} is
 * the IPP attribute name. The enumeration's integer value is the IPP enum
 * value. The {@code toString()} 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.
