/**
 * Class {@code Sides} is a printing attribute class, an enumeration, that
 * specifies how print-stream pages are to be imposed upon the sides of an
 * instance of a selected medium, i.e., an impression.
 * <p>
 * The effect of a {@code Sides} attribute on a multidoc print job (a job with
 * multiple documents) depends on whether all the docs have the same sides
 * values specified or whether different docs have different sides values
 * specified, and on the (perhaps defaulted) value of the
 * {@link MultipleDocumentHandling MultipleDocumentHandling} attribute.
 * <ul>
 *   <li>If all the docs have the same sides value <i>n</i> specified, then any
 *   value of {@link MultipleDocumentHandling MultipleDocumentHandling} makes
 *   sense, and the printer's processing depends on the
 *   {@link MultipleDocumentHandling MultipleDocumentHandling} value:
 *   <ul>
 *     <li>{@code SINGLE_DOCUMENT} -- All the input docs will be combined
 *     together into one output document. Each media sheet will consist of
 *     <i>n</i> impressions from the output document.
 *     <li>{@code SINGLE_DOCUMENT_NEW_SHEET} -- All the input docs will be
 *     combined together into one output document. Each media sheet will consist
 *     of <i>n</i> impressions from the output document. However, the first
 *     impression of each input doc will always start on a new media sheet; this
 *     means the last media sheet of an input doc may have only one impression
 *     on it.
 *     <li>{@code SEPARATE_DOCUMENTS_UNCOLLATED_COPIES} -- The input docs will
 *     remain separate. Each media sheet will consist of <i>n</i> impressions
 *     from the input doc. Since the input docs are separate, the first
 *     impression of each input doc will always start on a new media sheet; this
 *     means the last media sheet of an input doc may have only one impression
 *     on it.
 *     <li>{@code SEPARATE_DOCUMENTS_COLLATED_COPIES} -- The input docs will
 *     remain separate. Each media sheet will consist of <i>n</i> impressions
 *     from the input doc. Since the input docs are separate, the first
 *     impression of each input doc will always start on a new media sheet; this
 *     means the last media sheet of an input doc may have only one impression
 *     on it.
 *   </ul>
 *   <ul>
 *     <li>{@code SINGLE_DOCUMENT} -- All the input docs will be combined
 *     together into one output document. Each media sheet will consist of
 *     <i>n<sub>i</sub></i> impressions from the output document, where <i>i</i>
 *     is the number of the input doc corresponding to that point in the output
 *     document. When the next input doc has a different sides value from the
 *     previous input doc, the first print-stream page of the next input doc
 *     goes at the start of the next media sheet, possibly leaving only one
 *     impression on the previous media sheet.
 *     <li>{@code SINGLE_DOCUMENT_NEW_SHEET} -- All the input docs will be
 *     combined together into one output document. Each media sheet will consist
 *     of <i>n</i> impressions from the output document. However, the first
 *     impression of each input doc will always start on a new media sheet; this
 *     means the last impression of an input doc may have only one impression on
 *     it.
 *     <li>{@code SEPARATE_DOCUMENTS_UNCOLLATED_COPIES} -- The input docs will
 *     remain separate. For input doc <i>i,</i> each media sheet will consist of
 *     <i>n<sub>i</sub></i> impressions from the input doc. Since the input docs
 *     are separate, the first impression of each input doc will always start on
 *     a new media sheet; this means the last media sheet of an input doc may
 *     have only one impression on it.
 *     <li>{@code SEPARATE_DOCUMENTS_COLLATED_COPIES} -- The input docs will
 *     remain separate. For input doc <i>i,</i> each media sheet will consist of
 *     <i>n<sub>i</sub></i> impressions from the input doc. Since the input docs
 *     are separate, the first impression of each input doc will always start on
 *     a new media sheet; this means the last media sheet of an input doc may
 *     have only one impression on it.
 *   </ul>
 * </ul>
 * <p>
 * <b>IPP Compatibility:</b> The category name returned by {@code getName()} is
 * the IPP attribute name. The enumeration's integer value is the IPP enum
 * value. The {@code toString()} method returns the IPP string representation of
 * the attribute value.
