At that point I believe Atom differs - it doesn't add new statements, it 
modifies existing ones (hence the 'modified' date). Once 
content=content3 has been declared, content2 is flushed from the 
universe. Ok, older versions can be preserved, but they don't have to 
be, they aren't really an essential part of the model.

Maybe it might be more accurate to step outside the local Atom model and 
consider each entry as an ordered list, but given that few applications 
make use of the diffs it seems unnecessary.

Cheers,
Danny.
