Use of dfn (define) and title

Hi,

How do I actually use the <[b]dfn[/b]> tag?

I previously thought I was supposed to use it like this:

[CODE]<dfn>Opera</dfn> is a spesific web browser, like Internet Explorer only better.[/CODE]

But I’ve seen pages lately using it with <strong>title</strong> to explain things. Like [url=http://feedburner.com/]FeedBurner[/url] done (look for dotted underlines):

[CODE]Type Your Blog or Feed <dfn title=”URL of your blog (or feed, if you know it)”>Address</dfn> Here to Get Started:[/CODE]

Can I use it like this and are there any guidelines for this kind of use of the dfn tag?

Also in #HTML _↴
