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
