I created a minimal test case for you to try. http://mikemoreau.com/dev/html-open.html When I validate this url it passes the test when it should not. Am I misunderstanding this or is there a problem with the script? Thanks! 55707 1 ville.skytta 2011-08-23 18:55:38 +0000 The opening html tag is optional in HTML 4.01: http://www.w3.org/TR/html401/struct/global.html#edef-HTML I'm not sure about HTML 5, but in any case, http://validator.nu passes your test case as valid too, which means that if this is an error, the bug should be reported according to the validator.nu bug reporting instructions: http://about.validator.nu/#reporting-bugs
