I don't think this works without further restructuring. Essentially, 
'unevaluatedProperties' on works on a single level. So every level has 
to define all properties at that level either directly in 
properties/patternProperties or within a $ref.

See how graph.yaml is structured and referenced for an example how this 
has to work.

Dropping this means any undefined properties in port nodes won't be an 
error. Once I fix all the issues related to these missing, there will be 
a meta-schema checking for this (this could be one I fixed already).

This should certainly be changed though. We should only have 'true' for 
incomplete collections of properties. IOW, for common bindings.
