/**
 * Class MediaSize is a two-dimensional size valued printing attribute class 
 * that indicates the dimensions of the medium in a portrait orientation, with 
 * the X dimension running along the bottom edge and the Y dimension running 
 * along the left edge. Thus, the Y dimension must be greater than or equal to 
 * the X dimension. Class MediaSize declares many standard media size
 * values, organized into nested classes for ISO, JIS, North American,
 * engineering, and other media. 
 * <P>
 * MediaSize is not yet used to specify media. Its current role is
 * as a mapping for named media (see {@link MediaSizeName MediaSizeName}).
 * Clients can use the mapping method
 * <code>MediaSize.getMediaSizeForName(MediaSizeName)</code>
 * to find the physical dimensions of the MediaSizeName instances
 * enumerated in this API. This is useful for clients which need this 
 * information to format & paginate printing.
 * <P>
