[Building Sakai] Profile 2 and IE8 issue

That particular case might have been Quirks mode:

Quirks mode in any version of IE will also be triggered if anything but whitespace precedes the DOCTYPE. For example, if a hypertext document contains a comment or any tag before the DOCTYPE, IE will use quirks mode:

Apparently fixed in IE7 though. 

cheers,
Steve

Best to double check that we don't have some other places that might trigger a bang. Nuno can you advise, is it just an HTML page using a certain javascript method with a specific HTML tag in the page?
