LS, I'm teaching a course on Web technology and my student assistents have just informed me that w3.org currently fails to resolve HTTP requests on popular DTDs such as
http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd http://www.w3.org/TR/xhtml-basic/xhtml-basic11.dtd etc. I hope this message helps you improve the w3.org website, Regards, Jacco van Ossenbruggen
