Thanks for info, based on it I was just trying to update the old
list address for http://dir.gmane.org/gmane.org.w3c.validator.feed
with the new google address, but I found that somebody (maybe you)
did this already back in July.

Sounds like a good approximation of RFC 3696.  Beware of the ugly
domain literals.  Maybe catch 'localhost' as "not good enough" no
matter what your DNS server says.  If it's no domain literal it must
have at least one dot for RFC 2821 and I-D 2821bis.

So far for RSS 2.0 ;-)
