This is my source code file in Eclipse:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<!--[if lt IE 9]>
<script src="http://html5shim.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->
</head>
<body>
</body>
</html>
When I view this in IE9 it renders the text:
<!--[if lt IE 9]> <script src="http://html5shim.googlecode.com/svn/trunk/html5.js"></script> <![endif]-->
If I view source it says:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<!--[if lt IE 9]>
<script src="http://html5shim.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->
</head>
<body>
</body>
</html>
Any reason why the source has changed once served by the Faces Servlet?

This method allows you to use simple code in your HTML to detect Internet Explorer (IE). You can determine whether or not the end user is using IE, and if so, which version. This allows you to provide content based on which browser is being used.
Conditional comments are conditional statements interpreted by Microsoft Internet Explorer versions 5 through 9 in HTML source code. They can be used to provide and hide code to and from these versions of Internet Explorer.
Known issue, JSF rendering escapes the comments. You can solve it by using <h:outputText escape="false"> and HTML entities. You can also use OmniFaces <o:conditionalComment> to solve it in a nicer manner. See also the showcase site:
The
<o:conditionalComment>renders a conditional comment. Conditional comments are an IE specific feature which enables the developer to (out)comment blocks of HTML depending on whether the client is using IE and if so even which version. They are often seen in combination with CSS stylesheets like so:<!--[if lte IE 7]> <link rel="stylesheet" href="ie6-ie7.css" /> <![endif]-->However, Facelets renders the comment's contents HTML-escaped which makes it unusable.
<!--[if lte IE 7]> <link rel="stylesheet" href="ie6-ie7.css" /> <![endif]-->Also, if
javax.faces.FACELETS_SKIP_COMMENTScontext param is set totruethen it will even not be rendered at all. You would need to workaround this with an ugly<h:outputText escape="false">.<h:outputText value="<!--[if lte IE 7]><link rel="stylesheet" href="ie6-ie7.css" /><![endif]-->" escape="false" />This component is designed to solve this problem.
<o:conditionalComment if="lte IE 7"> <link rel="stylesheet" href="ie6-ie7.css" /> </o:conditionalComment>Note that you cannot use this with
<h:outputStylesheet>as it would implicitly be relocated as direct child of<h:head>.

This works:
<h:outputText escape="false" value="<!--[if lt IE 9]> <script src="http://html5shim.googlecode.com/svn/trunk/html5.js"></script> <![endif]-->"></h:outputText>
