/**
 * 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>
