What does this tag mean?



I have come across many websites and I've seen a tag, but I don't know exactly what it is used for, may be rss feed or anything else. I don't know for sure.
<link rel="alternate" type="application/rss+xml" title="TIPinAsia News" href="/TH/rss-news.php" />

Could someone help explain to me the way it works and how to use it? And also the url of this tutorial if any.
And sorry if I post in the wrong place, but I don't know where to post it.

Thanks in advance.

its a link tag for the RSS feed, as many browsers have support for detecting such feeds. For instance in Firefox i see the icon showing that the feed is present
Thanks for your reply!

And could you tell me where can I find the tutorial about it.

Thanks in advance,

well.. devshed.com has some tutorials about how to build an rss feed, otherwise its just a matter of "googling" for it..
Search for something like: "building RSS feed with PHP"
