Can I have multiple rel="alternate" tags for a webpage?

Question

In My site I have used rel="alternate" for RSS as follows

<link rel="alternate" type="application/rss+xml" title="RSS 2.0" href="http://www.mydomain.com/rss" />

Now I want to add another rel="alternate" tag for the mobile site as

<link rel="alternate" media="handheld" href="http://m.mydomain.com" />

Is there any issue to use multiple rel="alternate" tags in a page or no any effect to the SEO?

Answer 1

It's no problem, quite the contrary, it's even encouraged.

E.g. to link to several translations of a page; see the example in HTML 4.01: Links and search engines. Or to link to several different feeds; see the example in HTML5: Link type "alternate". Or to link to several different (= alternative) stylesheets.

There soesn't seem to be any problem using multiple instances according to this page:
