I have www.mysite.it that support 2 language:
mysite.it/it => italian language
mysite.it/en => english language
How can I set up the correct sitemap for the 2 version? Thanks
Google have specifically answered this here:

For example:
<url>
<loc>http://mysite.it/it</loc>
<xhtml:link rel="alternate" hreflang="en" href="http://mysite.it/en" />
<xhtml:link rel="alternate" hreflang="it" href="http://mysite.it/it" />
</url>
You will need to know the language or country code in order to be able to categorize other language types
