I'm using Word 2008 on a Mac. When I make a simple text html web page with Word, I go into the text and manually add

<link rel="shortcut icon" href="./favicon.ico">

which puts a favicon on my web page. But when I open that document in Word and resave it, that favicon "link rel" command disappears, as does my favicon in the displayed document. Why? Can I convince my Word to leave it in? Is there some more Word-compliant way to add favicons to html documents? Would a more modern version of Word make this easier?
