title: Fixing obsolete and missing attributes in <object> tag
body: <p>so I've looked (literally) almost all night trying to figure out how to fix these validation errors I've received through the validator and I don't know how to resolve them:
  <a href="https://i.stack.imgur.com/kc1dO.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/kc1dO.jpg" alt="enter image description here"></a></p>
  
  <p>And the HTML code:</p>
  
  <pre><code>&lt;object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="533" height="400" id="FlashID" title="Procedures Slides"&gt;
    &lt;param name="movie" value="assets/slides.swf"&gt;
    &lt;param name="quality" value="high"&gt;
    &lt;param name="wmode" value="opaque"&gt;
    &lt;param name="swfversion" value="11.2.0.0"&gt;
    &lt;!-- This param tag prompts users with Flash Player 6.0 r65 and higher to download the latest version of Flash Player. Delete it if you don’t want users to see the prompt. --&gt;
    &lt;param name="expressinstall" value="Scripts/expressInstall.swf"&gt;
    &lt;!-- Next object tag is for non-IE browsers. So hide it from IE using IECC. --&gt;
    &lt;!--[if !IE]&gt;--&gt;
    &lt;object type="application/x-shockwave-flash" data="assets/slides.swf" width="533" height="400"&gt;
      &lt;!--&lt;![endif]--&gt;
      &lt;param name="quality" value="high"&gt;
      &lt;param name="wmode" value="opaque"&gt;
      &lt;param name="swfversion" value="11.2.0.0"&gt;
      &lt;param name="expressinstall" value="Scripts/expressInstall.swf"&gt;
      &lt;!-- The browser displays the following alternative content for users with Flash Player 6.0 and older. --&gt;
      &lt;div&gt;
        &lt;h4&gt;Content on this page requires a newer version of Adobe Flash Player.&lt;/h4&gt;
        &lt;p&gt;&lt;a href="http://www.adobe.com/go/getflashplayer"&gt;&lt;img src="http://www.adobe.com/images/shared/download_buttons/get_flash_player.gif" alt="Get Adobe Flash player" width="112" height="33" /&gt;&lt;/a&gt;&lt;/p&gt;
      &lt;/div&gt;
      &lt;!--[if !IE]&gt;--&gt;
    &lt;/object&gt;
    &lt;!--&lt;![endif]--&gt;
  &lt;/object&gt;
