That's not exactly the same, though it's close.  The major difference is that with the different MIME type, IE will do nothing with it at all - pop a "save as" dialog, I think - so it is not possible to use it (unless you configure your server to send it as text/html).  You can use <!DOCTYPE html> today - although virtually no one does today.
