                     The page seems to contain a navigation bar. Ensure that
                     navigation bars across the site are consistent.
                     	 
                  </p>

                  <p>
                     Look at all the navigation bars in the site and ensure that they
                     are as consistent as possible in the ordering, positioning, formatting
                     and labeling of their links.
                     	 
                  </p>
                  
               </td>
            </tr>
            <tr>
               <td colspan="2" class="clearseparation">&nbsp;</td>
            </tr>
            <tr>
               <td colspan="2" class="clearseparation">&nbsp;</td>
            </tr>
            <tr>
               <td valign="top" colspan="2" class="description"><b>Issue Explanation</b><br>
                  
                  
                  <p>
                     Consistency is a key factor for achieving an accessible and usable
                     site. In fact, if a feature (like a navigation bar) is used
                     consistently through the pages of the site, the visitor will quickly
                     grasp the meaning of the navigation bar, and of its buttons/links, and
                     will be able to use it without hesitation.
                     	 
                  </p>
                  
                  <p>
                     If, on the other side, a group of links keeps changing from page to
                     page, then a visitor has to re-learn it each time it appears. This is
                     time consuming, requires effort on the user and is more error prone
                     (the user might click involuntarily on a link).
