Sitemap.xml generation only contains relative links if no fcdn is defined inside site configuration
If a site configuration only has a simple base entry like this:
A generated sitemap.xml only contains relative links, which prevent search engines to properly index all pages.
Additional crawler extensions like EXT:sitecrawler, who uses a valid sitemap (with absolute links) for a cache warm up, will fail.
To make developers life a bit sunnier, a hint comment inside the generated sitemap xml would be great:
"Add a FQDN to side configuration to get absolute paths"
A hint inside the site configuration modul, that the base setting also affects the sitemap generation, whould be usefull as well.
