SDC users need to compose one or more VNFs and the Virtual Links that connect them in NS

• The NSD and its referenced VNF / CNF versions should be matched. 
• During SDC references VNFs, SDC needs to validate the version of VNFs / CNF, based on the VNF / CNF descriptor metadata (version indicator in the metadata)
  • After 2.6.1, there is a version indicator in the metadata

Note:  cover the VNF version validation... SAP descriptor has a version...
