+     * The marking operations for drawing a page are stored in a stream that is the value of the
+     * <B>Contents</B> key in the Page object's dictionary. Each marking context includes a list
+     * of the named resources it uses. This resource list is stored as a dictionary that is the
+     * value of the context's <B>Resources</B> key, and it serves two functions: it enumerates
+     * the named resources in the contents stream, and it established the mapping from the names
+     * to the objects used by the marking operations.<BR>
+     * This object is described in the 'Portable Document Format Reference Manual version 1.3'
+     * section 7.5 (page 195-197).
