Actually, the "<!DOCTYPE" part is absolutely _required_ to be a valid HTML document.

The way that this whole thing works in every browser except IE is that the
server tells the browser what type of data it's sending and the browser acts
accordingly.  This server is telling us that it's sending text/plain data (HTML
is text/html).
IE shows the page because it violates the quite clear rule that the server
determines the data type -- IE ignores the server type and scans the file trying
to decide the type on its own... Quite often this leads to serious problems, as
it happens.
