The following errors are observed in the properties generated by the ETSI NSD plugin:

• The properties from tosca.nodes.nfv.NS appear as inputs as well as properties. They should only appear as properties
• Properties with null values are added to the node template
• the valid value constraint is being applied to all properties regardless of whether it is coming from tosca.nodes.nfv.NS or the type derived from it. This should only be the case for the properties from tosca.nodes.nfv.NS
• properties with "_" in the name are being truncated in the node templates
