PubSubHubbub Core 0.4: Validation vs. verification of intent

Hello,


I found it hard to wrap my head around that there is a difference
between "validation" and "verification of intent", since I thought that
verifying the intent by calling the callback is a kind of validation
already.

Maybe it would help if an example for a validation rule/process would be
added to the spec.
