      This type represents attribute modifications that were performed on an "Individual VNF instance" resource 
      when changing the current VNF package. The attributes that can be included consist of those requested to 
      be modified explicitly in the "ChangeCurrentVnfPkgRequest" data structure, and additional attributes of the 
      "VnfInstance" data structure that were modified implicitly during the operation.

      NOTE 1:	This attribute represents the delta (semantics as per IETF RFC 7396, JSON Merge Patch) between the value 
              of the attribute at the start of the "Change current VNF package" operation and the value of the attribute 
              at its completion.
      NOTE 2:	If present, this attribute (which depends on the value of the "vnfdId" attribute) was modified implicitly 
              during the related operation and contains a copy of the value of the related attribute from the VNFD in the 
              VNF Package identified by the "vnfdId" attribute.
