                     The page contains proprietary tags that are replaced by a
                     web server by one or more HTML tags. As a result, it is not
                     possible to check the accessibility of the original file. A
                     thorough evaluation requires testing the final version of
                     the page, which can be done by opening the page in a
                     browser, saving it, and testing the saved version.

                     Using a browser, request the page from the server. The page
                     that opens in your browser should no longer contain any
                     proprietary tags. Save the page using the browser's save
                     command (in Microsoft Internet Explorer, choose File &gt;
                     Save As), then test the saved version for accessibility.

                     Some web technologies such as ColdFusion use specialized
                     tags to create specific kinds of information and behaviors.
                     When the server receives a request for the page, the server
                     replaces all the specialized tags with HTML and then sends the
                     page to the user's browser. The page the user receives
                     should no longer contain any proprietary tags.
                     
                  </p>
                  
                  
                  <p>
                     It may not be possible to check the accessibility of a page
                     for the following reasons:
                     
                  </p>
                  
                  
                  <ul>
                     
                     <li>
                        The site may contain pages such as ColdFusion and ASP.NET
                        pages that are dynamically created
                        
                     </li>
                     
                     
                     <li>
                        Local pages may be part of a larger site that need to be
                        tested globally
                        
                     </li>
                     
                     
                     <li>
                        Local pages may contain special proprietary tags that are
                        replaced by the web server before delivering the page to
                        the user's browser
                        
                     </li>
                     
                     
                     <li>
                        For online pages, one can test also actual download times
                        and server response times
                        
                     </li>
                     
                     
                     <li>
                        The server may deliver slightly different pages to
                        different browsers
                        
                     </li>
                     
                     
                     <li>
                        Pages may contain links external to the website
                        
                     </li>
                     
                  </ul>
                  
                  
                  <p>
                     For these reasons, it is not always possible to completely
                     check the accessibility of a page in its original state.
                     You must test it in its final state.
