Re: domains pointing to same webspace & sitemaps

I've also got multiple domain names pointing to the same webspace. I
don't have 301 re-directs as the multiple names are taken care of by my
web host. For example, my main domain name is
www.thecareerbreaksite.com. If you enter www.thecareerbreaksite.co.uk,
you get the same homepage displayed.
I can obviously have only one sitemap, as I've only got one website.
Should the other domain names be listed in it, eg.
<loc>http://www.thecareerbreaksite.com/</loc>
<loc>http://www.thecareerbreaksite.co.uk/</loc>
