/**
 * Class 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 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>
 * SINGLE_DOCUMENT -- The result will be <I>n</I> copies of a single output
 * document comprising all the input docs.
 * <P>
 * <LI>
 * 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.
 * <P>
 * <LI>
 * 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.
 * <P>
 * <LI>
 * 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()</CODE> gives the IPP attribute
 * name.
 * <P>
