Sam Ruby responds to Brian Kelly's post about the RSS Validator and its treatment of RSS 1.0, or rather, RSS 1.0 modules. As Ruby notes:

"There is no question that RSS 1.0 is widely deployed. RSS 1.0 has a minimal core. The validation for that core is pretty solid."

Not sure if I'd seen that RSS comparison table before, but it is reassuring. (Oh, and see the really simple case off to the right. ;)

Good point, anyway about contributing test cases. I guess we should really submit a PRISM test case. And yes, the Validator is somewhat buggy as some recent testing confirms. On which more later.
