    You explained this very difference to me once. Comments may not 
exist in the DOM for XHTML-compliant UAs. "Ignore", it both forms, 
provides a way of commenting out code while still keeping it in the DOM 
for XHTML.

    Why does it need a link between it and other attributes? You use it 
on contents that you want ignored. Simple.
