- * memory if there are forward references.
- * The page is cloneable so the page master can make copies of
- * the top level page and regions.
+ * This class gathers all of of the components necessary to set up the basic
+ * page area precursors for the resolution of <code>fo:flow</code> and
+ * <code>fo:static-content</code> elements.
