Thanks!

I recall that I've read something about an on-the-fly conversion, but I
lost the reference.  Chances are that something like this is what it was
about.

That would probably be https://atom.geekhood.net/ (found in the XSL file).

I guess I could use this.  I usually have xsltproc lying around on the
systems where I read news.  I can probably live without the optional PHP
stuff (which I don't have).  It has its hacky parts (e.g. assuming that
Atom always gets assigned the "empty" namespace), but should work quite
well in practice.

Hm.  I wonder... since Emacs is (per default) built with libxml2, maybe
this can be leveraged to do this directly in Emacs... there's
libxml-parse-xml-region... maybe I should look at that.

Again, thanks for the hints!
