On the Web, the "extension" of a URL has no actual force, for the most
part.  The Content-Type sent by the Web server is what has force.  The
Web server often looks at the extension to know which Content-Type to
send, which is something the validator also told you:

Your Web server probably has no idea what "dwt" means, so it sends as
application/octet-stream (i.e., "this is a stream of bytes and I don't
know what kind of thing it represents").  That means that the
validator doesn't receive any information on what kind of thing it's
supposed to be either.  (I don't _think_ the validator actually looks
at extensions itself, only the Content-Type header, though I haven't
confirmed that.)

Well, that depends.  What _is_ a ".dwt" file?  Is there a MIME type
for it?  Is it supposed to be interpreted as HTML, or XHTML, or what?
From the file to which you pointed, it looks like it's supposed to be
some approximation of HTML 4.01 Transitional that uses hot comments to
signal things to the authoring tool, but there's no obvious way for me
to tell with certainty what you're trying to do, much less for the
validator to tell.
