It certainly does depend on your definition of extensible. Saying RSS2.0 is extensible because I can drop in namespaced blocks is like saying my copy of the K&R is extensible because I can write notes in the margins.
In practice, this objection is meaningless. There are a number of namespaced modules that are used in RSS 2.0, and most aggregators understand them. And the ones that don't bypass them without a problem.
This objection comes up all the time - and while there's a grain of truth to it, it's mostly nonsense
That depends entirely on the application you have in mind. For end- aggregators, it's mostly fine that they can ignore things they don't understand. But what about aggregating intermediaries? Unless there's a defined extensibility model, there's a large chance that the extra data in the exensions that the aggregator doesn't understand will be lost. RDF in RSS 1.0 make this a very simple problem to solve, whereas arbitrary XML namespaces makes it fiendishly difficult.
