How to comment out IE conditional comments?

Question

I'm just wondering if it's possible to comment out IE conditional comments themselves (for testing purposes)? The following does not work:

<!-- <!--[if IE 7]> some code <![endif]--> -->

Thanks in advance! flexx

Answer 1

No, it isn't possible.

SGML/HTML/XML/XHTML comments cannot be nested.

Answer 2

I think you can just insert something to make them invalid:

<!--\[if IE 7]> some code <!\[endif]-->
