The same could be said about Atom, with extensions to it. I'm reluctant to enumerate them all, because a) there's a question of precedence then, and b) it's an open list; more can always be defined.

The update time of an RSS 2 item can be determined by atom:updated or dcterms:modified, or pubDate if both of the above do not present. Should this be mentioned?

OK, this is what I currently have; comments?

Appendix B.  Use in RSS 2.0

   As previously noted, while this specification's extensions are
described in terms of the Atom feed format, they are also useful in
   similar formats.  This informative appendix demonstrates how they
can
   be used in an RSS 2.0-formatted [9] feed.

In RSS 2.0-formatted feeds, two entries are duplicates if they have
   the same guid element.  The update time of an entry is not
defined by
   RSS 2.0, but the feed-level update time can be determined by the
   lastBuildDate element, if present.

      <description>Before man travels to Mars, NASA hopes to
      design new engines that will let us fly through the Solar
