The HTML 4.01 specification indicates specifies the following DTD to be used in the <!DOCTYPE> specifier: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/loose.dtd"> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/frameset.dtd"> However your web site does not publish the DTD at the indicated addresses, because there is no "/TR/html4/" path, but instead the documents are in "/TR/html40/". I think that there's no need to change the specification, however your web site should include a symbolic link in the "/TR/" folder from "html4/" to "html40/", so that the DTD can be successfully described. I think this is an issue with external HTML validators, which try to check the reference to the DTD (to update its cached definition). But if the DTD does not exist, many validators ignore the <!DOCTYPE> element, and figure out its own "compatibility-mode" DTD, which does not enforce 4.01 rules. You can see the problem when using the online HTML validator from http://www.netmechanic.com/ (click on the "HTML Check & Repair" tool). Most of time, NetMechanic does not validate attributes specified in HTML 4.01 like "id=", "hreflang=", ... and it signals an error in the DTD specified for the document: this is because the 4.01 specification can not be found, and then NetMechanic uses the previous 4.0 specification only ! http://www.w3.org/TR/REC-html40/strict.dtd http://www.w3.org/TR/REC-html40/loose.dtd http://www.w3.org/TR/REC-html40/frameset.dtd
