Good morning (over here), the W3C Markup Validator  disagrees with this output from ox-html (which I reduced to the essential parts): #+begin_src html <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en"> <head> <title>This does <b>not</b> work</title> </head> <body><p></p></body></html> #+end_src Best wishes Jens  https://validator.w3.org/#validate_by_input
