I generated a sitemap with this tool: http://www.angeldigital.marketing/image-sitemap/
It spat out this code:
...
<url>
<loc>http://example.com/page</loc>
</url>
<url>
<loc>http://example.com/page.html</loc>
</url>
<url>
...
In my .htaccess file, I'm hiding .html, so example.com/page.html displays as example.com/page.
My question is, should the sitemap include both locations? If not, which one is preferable?
