Warning Mismatch between Public and System identifiers in the DOCTYPE declaration This document uses an inconsistent DOCTYPE declaration. The Public Identifier -//W3C//DTD HTML 4.0//EN declares the HTML 4.0 Strict document type, but the associated System Identifier http://www.w3.org/TR/html4/strict.dtd does not match this document type. The recommended System Identifier for HTML 4.0 Strict is http://www.w3.org/TR/1998/REC-html40-19980424/strict.dtd. The safest way to use a correct DOCTYPE declaration is to copy and paste one from the recommended list and avoid editing that part of your markup by hand. ]] So I looked at the recommended list, and it says that I should use http://www.w3.org/TR/html4/strict.dtd. Please clarify this. 55734 1 ville.skytta 2011-08-23 21:13:13 +0000 The recommended list at http://www.w3.org/QA/2002/04/valid-dtd-list.html has http://www.w3.org/TR/html4/strict.dtd, but it's HTML 4.01 Strict, and the posted warning message indicates your document is HTML 4.0 (not 4.01) Strict. There are no HTML 4.0 entries in that recommended list, and I'm not aware of a better suggestion for it than what the validator currently suggests. If you do have one, feel free to post it and reopen this bug.
