I've been looking at the 'Microformat' rel="tag", but am a little confused as to its propper use.
From the spec:
By adding rel="tag" to a hyperlink, a page indicates that the destination of that hyperlink is an author-designated "tag" (or keyword/subject) for the current page.
What do they mean by the 'destination of the hyperlink' is a 'tag'?
In what situations might it be used?
