I don't think this should be added here because users must define what 
each port is. With it here, we're going to validate the nodes twice as 
well. Same can be said for 'port' though. It can't be extended though.

I originally wanted to a do a meta-schema to enforce some of this, but 
there's just too many exceptions.
