I found this draft tip: Don't forget to add a doctype - Quality Web Tips http://www.w3.org/2001/06tips/Doctype but I don't think it actually motivates adding a DOCTYPE. Does anybody have any evidence that "browsers may not behave correctly if you don't set a proper Doctype"? I think HTML documents should begin like this... <html xmlns="http://www.w3.org/1999/xhtml"> <head> ... That provides all the information I need to manage the document (i.e. find markup errors using automated tools) and all the information readers need in order to understand it. I know the HTML 4 and XHTML 1.x specs are still limited by the fact that DTDs are much more widely deployed than schemas, but that doesn't really say why users should bother with a doctype declaration. The best motivation I can find is... A doctype will allow you to use widely-deployed DTD-based tools (such as this validation service) to find likely errors in your document.
