/**
 * Class MultipleDocumentHandling is a printing attribute class, an enumeration,
 * that controls finishing operations and the placement of one or more
 * print-stream pages into impressions and onto media sheets. When the value of
 * the {@link Copies Copies} attribute exceeds 1, MultipleDocumentHandling also
 * controls the order in which the copies that result from processing the
 * documents are produced. This attribute is relevant only for a multidoc print
 * job consisting of two or more individual docs.
 * <P>
 * Briefly, MultipleDocumentHandling determines the relationship between the
 * multiple input (electronic) documents fed into a multidoc print job and the
 * output (physical) document or documents produced by the multidoc print job.
 * There are two possibilities:
 * <UL>
 * <LI>
 * The multiple input documents are combined into a single output document.
 * Finishing operations ({@link Finishings Finishings}),
 * are performed on this single output
 * document. The {@link Copies Copies} attribute tells how many copies of this
 * single output document to produce. The MultipleDocumentHandling values
 * SINGLE_DOCUMENT and SINGLE_DOCUMENT_NEW_SHEET specify two variations of
 * this  possibility.
 * <P>
 * <LI>
 * The multiple input documents remain separate output documents. Finishing
 * operations ({@link Finishings Finishings}),
 * are performed on each output document
 * separately. The {@link Copies Copies} attribute tells how many copies of each
 * separate output document to produce. The MultipleDocumentHandling values
 * SEPARATE_DOCUMENTS_UNCOLLATED_COPIES and SEPARATE_DOCUMENTS_COLLATED_COPIES
 * specify two variations of this possibility.
 * </UL>
 * <P>
 * In the detailed explanations below, if "<CODE>a</CODE>" represents an
 * instance of document data, then the result of processing the data in
 * document "<CODE>a</CODE>" is a sequence of media sheets represented by
 * "<CODE>a(*)</CODE>".
 * <P>
 * The standard MultipleDocumentHandling values are:
 * <UL>
 * <LI>
 * <A NAME="sdfi">{@link #SINGLE_DOCUMENT
 * <B><CODE>SINGLE_DOCUMENT</CODE></B>}</A>. If a print job has multiple
 * documents -- say, the document data is called <CODE>a</CODE> and
 * <CODE>b</CODE> -- then the result of processing all the document data
 * (<CODE>a</CODE> and then <CODE>b</CODE>) must be treated as a single sequence
 * of media sheets for finishing operations; that is, finishing would be
 * performed on the concatenation of the sequences <CODE>a(*),b(*)</CODE>. The
 * printer must not force the data in each document instance to be formatted
 * onto a new print-stream page, nor to start a new impression on a new media
 * sheet. If more than one copy is made, the ordering of the sets of media
 * sheets resulting from processing the document data must be
 * <CODE>a(*),b(*),a(*),b(*),...</CODE>, and the printer object must force
 * each copy (<CODE>a(*),b(*)</CODE>) to start on a new media sheet.
 * <P>
 * <LI>
 * <A NAME="sducfi">{@link #SEPARATE_DOCUMENTS_UNCOLLATED_COPIES
 * <B><CODE>SEPARATE_DOCUMENTS_UNCOLLATED_COPIES</CODE></B>}</A>. If a print job
 * has multiple documents -- say, the document data is called <CODE>a</CODE> and
 * <CODE>b</CODE> -- then the result of processing the data in each document
 * instance must be treated as a single sequence of media sheets for finishing
 * operations; that is, the sets <CODE>a(*)</CODE> and <CODE>b(*)</CODE> would
 * each be finished separately. The printer must force each copy of the result
 * of processing the data in a single document to start on a new media sheet.
 * If more than one copy is made, the ordering of the sets of media sheets
 * resulting from processing the document data must be
 * <CODE>a(*),a(*),...,b(*),b(*)...</CODE>.
 * <P>
 * <LI>
 * <A NAME="sdccfi">{@link #SEPARATE_DOCUMENTS_COLLATED_COPIES
 * <B><CODE>SEPARATE_DOCUMENTS_COLLATED_COPIES</CODE></B>}</A>. If a print job
 * has multiple documents -- say, the document data is called <CODE>a</CODE> and
 * <CODE>b</CODE> -- then the result of processing the data in each document
 * instance must be treated as a single sequence of media sheets for finishing
 * operations; that is, the sets <CODE>a(*)</CODE> and <CODE>b(*)</CODE> would
 * each be finished separately. The printer must force each copy of the result
 * of processing the data in a single document to start on a new media sheet.
 * If more than one copy is made, the ordering of the sets of media sheets
 * resulting from processing the document data must be
 * <CODE>a(*),b(*),a(*),b(*),...</CODE>.
 * <P>
 * <LI>
 * <A NAME="sdnsfi">{@link #SINGLE_DOCUMENT_NEW_SHEET
 * <B><CODE>SINGLE_DOCUMENT_NEW_SHEET</CODE></B>}</A>. Same as SINGLE_DOCUMENT,
 * except that the printer must ensure that the first impression of each
 * document instance in the job is placed on a new media sheet. This value
 * allows multiple documents to be stapled together with a single staple where
 * each document starts on a new sheet.
 * </UL>
 * <P>
 * SINGLE_DOCUMENT is the same as SEPARATE_DOCUMENTS_COLLATED_COPIES with
 * respect to ordering of print-stream pages, but not media sheet generation,
 * since SINGLE_DOCUMENT will put the first page of the next document on the
 * back side of a sheet if an odd number of pages have been produced so far
 * for the job, while SEPARATE_DOCUMENTS_COLLATED_COPIES always forces the
 * next document or document copy on to a new sheet.
 * <P>
 * In addition, if a {@link Finishings Finishings} attribute of
 * {@link Finishings#STAPLE <CODE>STAPLE</CODE>} is specified, then:
 * <UL>
 * <LI>
 * With SINGLE_DOCUMENT, documents <CODE>a</CODE> and <CODE>b</CODE> are
 * stapled together as a single document with no regard to new sheets.
 * <P>
 * <LI>
 * With SINGLE_DOCUMENT_NEW_SHEET, documents <CODE>a</CODE> and <CODE>b</CODE>
 * are stapled together as a single document, but document <CODE>b</CODE>
 * starts on a new sheet.
 * <P>
 * <LI>
 * With SEPARATE_DOCUMENTS_UNCOLLATED_COPIES and
 * SEPARATE_DOCUMENTS_COLLATED_COPIES, documents <CODE>a</CODE> and
 * <CODE>b</CODE> are stapled separately.
 * </UL>
 * <P>
 * <I>Note:</I> None of these values provide means to produce uncollated
 * sheets within a document, i.e., where multiple copies of sheet <I>n</I>
 * are produced before sheet <I>n</I>+1 of the same document.
 * To specify that, see the {@link SheetCollate SheetCollate} attribute.
 * <P>
 * <B>IPP Compatibility:</B> The category name returned by
 * <CODE>getName()</CODE> is the IPP attribute name.  The enumeration's
 * integer value is the IPP enum value.  The <code>toString()</code> method
 * returns the IPP string representation of the attribute value.
