Datatype: QoS
(Note: In model this is an abstract parent of NsQoS and VnfQoS. I recommend we create QoS in "common" with attributes as specified in the model, and then create VnfQoS and NsQos.
The QoS datatype specifies quality of service parameters applicable to a VL.
Applied )
It is the asbstract parent of the NsQos and VnfQos datatypes, as the NsQoS (QoS in ETSI GS NFV IFA 014) includes a priority attribute, while VnfQoS (QoS in ETSI GS NFV IFA 011) does not.
The QoS datatype specifies quality of service parameters applicable to a VL.

The LocalAffinityOrAntiAffinityRule describes the affinity or anti-affinity rule applicable between the virtualization containers to be created based on a particular VDU, or between internal VLs to be created based on a particular VnfVirtualLinkDesc.

Class: AffinityOrAntiAffinityGroup - missing in clean output
Note: This should probably go into common as it is applicable to NS and VNFs with the following definition:
The AffinityOrAntiAffinityGroup class describes the affinity or anti-affinity relationship.
For NSs, those rules are applicable between the VNF instances created using different VnfProfiles, the Virtual Link instances created using different VlProfiles or the nested NS instances created using different NsProfiles.
For VNFs, those rules are applicable between the virtualization containers to be created based on different VDUs, or between internal VLs to be created based on different VnfVirtualLinkDesc(s).
Per VNF, the affinity / anti-affinity rules defined using this class, using the LocalAffinityOrAntiAffinityRule datatypet, and using the placement constraints in the GrantLifecycleOperation as defined in ETSI GS NFV IFA 007 should be conflict-free. In case of conflicts, the placement constraints in the GrantLifecycleOperation shall take precedence
