Google Data feeds are Atom, and they definitely contain non-HTML;
indeed, except for Blogger I can't think of a single one that contains
any HTML at all.  Granted that data is not a typical use for Atom, it's
not unheard-of either.  LexisNexis is also using Atom for both data and
documents, both of which are in plain XML.  (Claimer: I used to work on
one, and I'm now working on the other.)
