You can use the http://validator.w3.org/detailed.html interface, which even lets you override a DOCTYPE in the document itself. Technically, this means a deviation from SGML principles. It is logically impossible to validate without a DTD, since validation means, by definition, checking a document against a DTD. And a DOCTYPE declaration is the way to specify a DTD. But being liberal we might regard the doctype selection menu as a tool for implicitly creating documents that have the DOCTYPE specified. > Ok, I > know this documents does not validate, and there should be some warning > about it, If a document does not validate, a validator must, by definition, issue an error message. > but for what are then tne fields for selecting charset and > doctype? It seems that you _have_ used the extended interface. Then I cannot see what you are referring to. > I mean I have a page. This page doesn't have a DOCTYPE. Ok, I know it's > not valid.

You can, since you can create a copy of the document and edit it for validation - though in rare cases, this might be regarded as copyright infringement. -- Jukka "Yucca" Korpela, http://www.cs.tut.fi/~jkorpela/
