This situation is totally unacceptable. In fact, it is so troubling
it negates all the effort jef and seth have put in on rpm and yum. Thus
they must commit hari-kari to restore the honor of fedora.
So, afaict you're either kidding or you're a jerk. I'm going to assume
you're kidding. :)
at this level there's nothing yum is doing at all.
I can _fix_ it by making the install of xml-commons\* a trueinstall and
manually removing the older xml-commons packages but that kinda defeats
the purpose of HAVING an update mode at all.
