/**
 * Class PageRanges is a printing attribute class, a set of integers, that 
 * identifies the range(s) of print-stream pages that the Printer object uses 
 * for each copy of each document which are to be printed. Nothing is printed 
 * for any pages identified that do not exist in the document(s). The attribute 
 * is associated with <I>print-stream</I> pages, not application-numbered pages 
 * (for example, the page numbers found in the headers and or footers for 
 * certain word processing applications). 
 * <P>
 * In most cases, the exact pages to be printed will be generated by a device 
 * driver and this attribute would not be required. However, when printing an 
 * archived document which has already been formatted, the end user may elect to 
 * print just a subset of the pages contained in the document. In this case, if 
 * a page range of <CODE>"<I>n</I>-<I>m</I>"</CODE> is specified, the first page 
 * to be printed will be page <I>n.</I> All subsequent pages of the document 
 * will be printed through and including page <I>m.</I> 
 * <P>
 * If a PageRanges attribute is not specified for a print job, all pages of 
 * the document will be printed. In other words, the default value for the 
 * PageRanges attribute is always <CODE>{{1, Integer.MAX_VALUE}}</CODE>. 
 * <P>
 * The effect of a PageRanges attribute on a multidoc print job (a job with 
 * multiple documents) depends on whether all the docs have the same page ranges 
 * specified or whether different docs have different page ranges specified, and 
 * on the (perhaps defaulted) value of the {@link MultipleDocumentHandling 
 * MultipleDocumentHandling} attribute. 
 * <UL>
 * <LI>
 * If all the docs have the same page ranges specified, then any value of {@link 
 * MultipleDocumentHandling MultipleDocumentHandling} makes sense, and the 
 * printer's processing depends on the {@link MultipleDocumentHandling 
 * MultipleDocumentHandling} value: 
 * <UL>
 * <LI>
 * SINGLE_DOCUMENT -- All the input docs will be combined together into one 
 * output document. The specified page ranges of that output document will be
 * printed. 
 * <P>
 * <LI>
 * SINGLE_DOCUMENT_NEW_SHEET -- All the input docs will be combined together 
 * into one output document, and the first impression of each input doc will 
 * always start on a new media sheet. The specified page ranges of that output 
 * document will be printed. 
 * <P>
 * <LI>
 * SEPARATE_DOCUMENTS_UNCOLLATED_COPIES -- For each separate input doc, the 
 * specified page ranges will be printed. 
 * <P>
 * <LI>
 * SEPARATE_DOCUMENTS_COLLATED_COPIES -- For each separate input doc, the 
 * specified page ranges will be printed. 
 * </UL> 
 * <UL>
 * <LI>
 * SEPARATE_DOCUMENTS_UNCOLLATED_COPIES -- For each separate input doc, its own
 * specified page ranges will be printed.. 
 * <P>
 * <LI>
 * SEPARATE_DOCUMENTS_COLLATED_COPIES -- For each separate input doc, its own
 * specified page ranges will be printed.. 
 * </UL>
 * </UL>
 * <P>
 * <B>IPP Compatibility:</B> The PageRanges attribute's canonical array form 
 * gives the lower and upper bound for each range of pages to be included in 
 * and IPP "page-ranges" attribute. See class {@link 
 * javax.print.attribute.SetOfIntegerSyntax SetOfIntegerSyntax} for an 
 * explanation of canonical array form. The category name returned by 
 * <CODE>getName()</CODE> gives the IPP attribute name. 
 * <P>
