xhtml frameset validation error

when inputting this code the validator seems to error. This code validates
with both xhtml strict, and xhtml transitional doctypes, but when using the
Frameset doctype, it returns an error message stating that the <body> tag is
not allowed here, and that the end tag </html> is not finished.  I'm quite
sure this is valid markup, so I can only conclude that there must be some
error with the validator.  Please let me know what is going on; I would like
to be able to make valid web pages using the frameset doctype, unless there
is a way to achieve the effect on this web page
http://eoncafe.com/feedback.html with valid xhtml strict

-------below is the code discussed--------------

<!DOCTYPE html
     PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN"
     "http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd">
      <html>
        <head>

          <title>Title</title>
        </head>

        <body>
          <!-- ... body of document ... -->
        </body>

      </html>
