Is it bad to host an XML sitemap in a different subdomain?

Example: sitemap.example.com/sitemap.xml for pages on www.example.com.

Google treats sub domains, almost as different domains.

I would keep sitemaps relative to their own subdomain.

Thanks Paul, what if there are limitations to posting the sitemap to another subdomain? Can Google connect the dots if sitemap.example.com is verified in your webmaster tools account and www.example.com/robots.txt points to the sitemap in the other subdomain?

It's still linked, so Google will still read it. I just honestly don't know how Google will interpret it.

Is this something that's in place? What is webmaster tools showing?
