/**
 * Class {@code Copies} is an integer valued printing attribute class that
 * specifies the number of copies to be printed.
 * <p>
 * On many devices the supported number of collated copies will be limited by
 * the number of physical output bins on the device, and may be different from
 * the number of uncollated copies which can be supported.
 * <p>
 * The effect of a {@code Copies} attribute with a value of <i>n</i> on a
 * multidoc print job (a job with multiple documents) depends on the (perhaps
 * defaulted) value of the
 * {@link MultipleDocumentHandling MultipleDocumentHandling} attribute:
 * <ul>
 *   <li>{@code SINGLE_DOCUMENT} -- The result will be <i>n</i> copies of a
 *   single output document comprising all the input docs.
 *   <li>{@code SINGLE_DOCUMENT_NEW_SHEET} -- The result will be <i>n</i> copies
 *   of a single output document comprising all the input docs, and the first
 *   impression of each input doc will always start on a new media sheet.
 *   <li>{@code SEPARATE_DOCUMENTS_UNCOLLATED_COPIES} -- The result will be
 *   <i>n</i> copies of the first input document, followed by <i>n</i> copies of
 *   the second input document, . . . followed by <i>n</i> copies of the last
 *   input document.
 *   <li>{@code SEPARATE_DOCUMENTS_COLLATED_COPIES} -- The result will be the
 *   first input document, the second input document, . . . the last input
 *   document, the group of documents being repeated <i>n</i> times.
 * </ul>
 * <p>
 * <b>IPP Compatibility:</b> The integer value gives the IPP integer value. The
 * category name returned by {@code getName()} gives the IPP attribute name.
