tosca_definitions_version: tosca_simple_yaml_1_0
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.
