   <p>The <code title="rel-up">up</code> keyword may be used with
   <code>link</code>, <code>a</code>, and <code>area</code>
   elements. For <code>link</code> elements, it creates a <span
   title="hyperlink link">hyperlink</span>.</p>
 
   <p>The <code title="rel-up">up</code> keyword indicates that the
   document is part of a hierarchical structure, and that the link is
-  leading to the document that is the parent of the current
+  leading to a document that is an ancestor of the current
   document.</p>
 
   <p>The <code title="rel-up">up</code> keyword may be repeated within
   a <code title="attr-hyperlink-rel">rel</code> attribute to indicate
   the hierarchical distance from the current document to the
-  referenced document. Each occurrence of the keyword represents one
-  further level. If the <code title="rel-index">index</code> keyword
-  is also present, then the number of <code title="rel-up">up</code>
-  keywords is the depth of the current page relative to the top of the
