Seconded.  But it's there, not only in distrbutions, but AFAIK vanilla
upstream kernel nowadays too.

That part is pretty trivial.  Just install the validator on a machine
that has SELinux in enforcing mode, then set SELinux into permissive
mode ("/usr/sbin/setenforce 0" on the fly or SELINUX=permissive
to /etc/selinux/config to get it applied after boot), and start using
the validator, watching /var/log/audit/audit.log on FC4
or /var/log/messages on FC3.

I've already done a part of this; I don't claim it to be complete or
error free, but it's a start.  See the commentary in the %prep section
of the specfile at
http://cvs.fedora.redhat.com/viewcvs/rpms/w3c-markup-validator/devel/w3c-markup-validator.spec?root=extras&rev=.&view=auto

I think I can do something about this this week, as I would like to test
0.7.0a2 on my FC4 box.

I tend to think theoretically yes.  But every time I've seen someone ask
it on the Fedora Extras or SELinux lists, the answer has been more or
less a blunt "this is not currently doable, wait until we have the
official way figured out".  I guess in the strict meaning of the word,
it is _doable_ now, but maybe just seen as ugly and thus frowned upon.
Or then again I might be missing something.

Yes, from FC4 and FC5 devel, for now.  It's still in FC3, but I have a
open ticket on that, it doesn't work there either:
