              definitions (NADs) the orchestrator has created as base for the network 
              interface the extCpdData represents. 
              Note 1: When the extCpdData represent a networkRedundant/mated-pair of 
              sriov interfaces, there are references to 2 or 3 related NADs needed 
              to be passed, while for other interface types only one NAD reference 
              is needed to be passed.
              Note 2: The format of the Content strings is specific for each different 
              orchestration templating technology used (Helm, Teraform, etc.). 
              Currently only a format for use with Helm charts is suggested:
              "<helmchartname>:[<subchartname>.]^(0..N)[<parentparamname>.]^(0..N)<paramname>".  
              Whether the optional parts of the format are present depends on how the 
              parameter is declared in the helm chart. An example is: 
              chartName:"subChart1.subChart2.subChart3.Parent1.Parent2.Parent3.nadName".
              Note 3: A direct attached (passthrough) network interface, such as an sriov 
              interface, attaches to a network via only one of the two switch planes 
              in the infrastructure.
              When using a direct attached network interface one therefore commonly in a 
              pod uses a mated pair of sriov network attachments, where each interface 
              attaches same network but via different switchplane.
              The application uses the mated pair of network interfaces as a single 
              logical “swith-path-redundant” network interface – and this is represented 
              by a single extCpdData. 
              Also there is a case where a third “bond” attachment interface is used in 
              the pod, bonding the two direct interfaces so that the application do not 
              need to handle the redundancy issues – application just uses the bond interface.
              In this case, all three attachments are together making up a logical 
              “switch-path-redundant” network interface represented by a single extCpdData. 
              When three NADs are used in the extCpdData the NAD implementing the bond attachment 
              interface is provided through the parameter indicated in the third place in 
              the nadNames attribute.

              Attribute may be omitted if the namespace is same as the application 
              namespace.
