+<body>
+       <h1>Taxonomy of Categories</h1>
+       
+       Facets are defined using a hierarchy of categories, known as a
+       <i>Taxonomy</i>
+       
+       <br>
+       For example, in a book store application, a Taxonomy could have the
+       following hierarchy:
+       <p>
+       <ul>
+               <li>Author</li>
+               <ul>
+               <li>Mark Twain</li>
+               <li>J. K. Rowling</li>
+               </ul>
+       </ul>
+       <ul>
+               <li>Date</li>
+               <ul>
+               <li>2010</li>
+               <li>2009</li>
+               </ul>
+       </ul>
+       
+       The <i>Taxonomy</i> translates category-paths into category-ordinal and vice versa.
