Is it okay to add id/class to <link> tag?

html

Solution

According to HTML 4.01 Transitional, `id`, `class` are document-wide selectors, and thus it is ok to have them in the `link` element.

Problem

Is it okay to do this? ``` <link rel="stylesheet" href="css/mobile/load.css" id="stylesheet_mobile" /> ``` so I can use JavaScript to dynamically disable stylesheets?
