Can the frameset element contain body?

Looking at the HTML 4.01 DTDs and recommendation regarding the NOFRAMES
element I've started wondering if it's at all legal, maybe even
required, to have a BODY element inside the NOFRAMES element.

In the HTML 4.01 Transitional DTD, which is where the NOFRAMES element
is specified, the rule for the content in it is defined as:

<![ %HTML.Frameset; [
<!ENTITY % noframes.content "(BODY) -(NOFRAMES)">

<!ENTITY % noframes.content "(%flow;)*">

As far as I've been able to understand from reading the introduction on
how to read the DTD, as well as looking closely at the frameset and
transitional DTDs for a while, the last rule is used when the document
is not in a frameset context.  The first, which is used in a frameset
context (due to the rule found in the frameset DTD), specifies that one,
and only one instance of BODY is _required_, and it can under no
circumstances contain another NOFRAMES element.  The NOFRAMES element is
then defined as:

<!ELEMENT NOFRAMES - - %noframes.content;
 -- alternate content container for non frame-based rendering -->

There's two examples of the usage of NOFRAMES in the HTML 4.01
recommendation, both using the frameset DTD, URLs
<URL: http://www.w3.org/TR/html4/present/frames.html#h-16.1 > and
<URL: http://www.w3.org/TR/html4/present/frames.html#h-16.4.1 >

Neither of these contain a BODY element inside the NOFRAMES element,
which is of course why I'm wondering what's the right thing to do.
