I'm glad you brought this up - I was trying to find a place in the documentation
to put it, but since target specific nodes would be a new trick for OPP I didn't
quite know how to go about doing it. Do we just list them as Optional: or
should we add a target specific section to the documentation and list them out
there instead?
