What is a <link> tag besides style sheets?

<link rel="stylesheet" type="text/css" href="example.css" />

With the link tag, we can determine the relationship type and the mime type, but I have never seen it. What are some examples of using real for other rel attributes ? What are the support issues?

I'm not sure what we can and cannot do with this tag, how the browser works with it, etc.

From my own game, it seems I can’t read any of the named data via JavaScript, but the browser is still dealing with the content.

I am sure that there is a quantity of infected resources for this.
