What do we need to know about the validator and TagExtraInfo for the certification. The manning book does not talk about these two topics, maybe because they are not in the objectives, but they ARE in the API so shouldn't we know it?

You said it -- they're not in the objectives so you don't need to know it for the exam -- but for your job, it might be a good thing to know. You'll notice there are a few topics missing from the exam -- like Filters -- how to actually USE a design pattern (not just what its benefits / uses are. For the exam you just need to know the stuff listed in the objectives, promise.
