description: >
  This template is a test template which contains invalid output
  needed for substitution mappings.
  The outputs defined by the topology template have to match the
  attributes of the node type or the substituted node template,
  and the observable attributes of the substituted node template
  have to be defined as attributes of the node type or outputs in
  the topology template.
  But this template contains output of my_cpu_output which is not
  defined in node type of example.TransactionSubsystem, so it will
  be validated error for substitution mappings.
