Using conditional comments as described in the article will actually hide the nested Object from all browsers: <!--[if !IE]> <object></object> <![endif]--> Therefore, it should be constructed in the following way in order to hide the nested Object only from Internet Explorer. However, this method won't validate which means it can't be used in XHTML 2.0: <![if !IE]> <object></object> <![endif]>

  I can't comment on xhtml but I've tested all the examples above as plain HTML and they don't work! However there is a syntax for 'down-level' (Microsofts' obnoxious label for browsers that aren't IE) CC's that works AND validates:

  
  <!--[if gte IE 6]><!-->
  Seen by all real browsers and IE 6. Validates as HTML 4.01 Transitional and possibly other doctypes
  <!--<![endif]-->

  
  Tested and working on Firefox 1.5, Opera 7.5, IE6, Konqueror and Lynx.

  
  The only problem I've found with this code is that it confuses the syntax highlighter built into the CFML module for Eclipse (causing it to render the remaining page in comment green).

  
  Thanks to Stu at cssplay.co.uk for finding this. I don't know where he found it but I'm grateful anyway. As usual the MS documentation was completely useless and even google failed to turn up much of value.

  You can embed the conditional comments like this:
  <!-- [if !IE] -->
  <object></object>
  <!-- <![endif] -->

  conditional comments has always seemed sort of an ugly hack to me, although if the focus starts to shift from IE as the development target of choice to IE as a legacy browser then they become perhaps more useful.
