Is there a way to change the attributes of the <html> tag at runtime?

I want to add a manifest attribute at runtime, so I can control when Appcache will load.

Example: if the user is correctly registered in the application,

<html>
// page content
</html>

changes to:

<html manifest="myapp.manifest">
// page content
</html>

Anyway, can I achieve this using javascript, jquery or anything else? I want to control when Appcache will be loaded conditionally. (I already read that there is another html in iFrame.)
