Reviewing..

Nitpick: Since these are all text and we are not actually introducing any cool HTML formatting, would it not be enough if we just add it to the processor's @CapabilityDescription itself?

I agree, although Additional Details pages are always helpful, in this case I think this information is more important to be on the "front page", and any Additional Details (such as examples) would go here.

@zenfenan updated.
