Let's clean this up right now, since I'm tired of people using different
wording to mean different things and confusing people.
All 0.91 files are valid 0.92 files.
Some 0.92 files are valid 0.91 files (plus elements).
All RSS 1.0 files are RSS 0.9 files (plus attributes and elements).
No RSS 0.9 and RSS 0.91 files are compatible
No RSS 0.91 and RSS 1.0 files are compatible.
or in a pretty chart:
_0.9_ _0.91_ _0.92_ _1.0_
_0.9__ All None None All
_0.91_ None All Some None
_0.92_ None All All None
_1.0__ None None None All
I think that's it, now I have to stick this at:
