unclear point in html 4.01 spec - radio buttons

by chance I found that there is one thing that the HTML 4.01
spec is not clear about.

The standard specifies that radio buttons are mutually exclusive
and that when one is on, the others must be off (17.2).

However, the standard does not specify what the user agent should
do if the HTML does not specify a default "on" button, i.e., when
all the buttons defaults to "off".

Right now, Netscape actually will display all-off buttons, but
lynx will arbitrary display the first button as "on".

And it's disheartening that there are actually sites using radio
buttons where the "all-off" case is in fact valid input :(
