Luc Boutier commented on TOSCA-161:
-----------------------------------

I think the definition of the Root node has something wrong: right now we have removed the Feature capability/dependency to replace it with a single dependency requirement of type tosca.capabilities.Root. 
But actually no nodes defines the tosca.capabilities.Root capability. I think it's not very correct to satisfy a requirement by something that doesn't match the type of the requirement (and we don't have node directly defining the tosca.capabilities.Root capability). 
To make it simpler and, I think, more correct, we should change the dependency definition so the requirement type is directly tosca.nodes.Root as I think any node can depends from another one. 

Woud be: 

  tosca.nodes.Root: 
    description: The TOSCA Node Type all other TOSCA base Node Types derive from 
    attributes: 
      tosca_id: 
        type: string 
      tosca_name: 
        type: string 
    requirements: 
      - dependency: 
        type: tosca.nodes.Root 
        lower_bound: 0 
        upper_bound: unbounded 
    interfaces: [tosca.interfaces.node.lifecycle.Standard | tosca.interfaces.node.lifecycle.Simple ]
