Sorry, but the reported errors are erroneous as you can see by looking at the errors messages.
This is error-free: <!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"; xmlns:v="urn:schemas-microsoft-com:vml"> <head> <meta http-equiv="Content-type" content="text/html;charset=UTF-8" /> <title>mytitle</title> </head> <body> <!-- - --> </body> </html> the validator reports: Congratulations The uploaded document was successfully checked as XHTML 1.0 Strict. This means that the resource in question identified itself as "XHTML 1.0 Strict" and that we successfully performed a formal validation using an SGML, HTML5 and/or XML Parser(s) (depending on the markup language used).
