I'm not going to let that go unchallenged.  The ability to put your own 
markup in a feed entry and be confident that it will not cause 
receiving software to break, and that it will be there for receiving 
software that actually knows how to deal with it, is what many people 
describe using the word "extensibility".  I think that Atom is, in a 
popular usage of the term (a large majority usage, I'd bet, but without 
backing statistics) extensible.

The people who insist that you have to have to buy into a 
graph-theoretical KR model to be able to use the word "extensible" live 
in a universe that is self-consistent, but it's not the one where I 
work. -Tim
