+To describe actions or workflows from within a service use:
+
+ * service_workflow_tasks: One or more workflow task properties
+
+which expects a map where the key is the step and the value a list of
+dictionaries descrbing each a workflow task, for example::

+ step3:
+ - name: external

+The Heat guide for the `OS::Mistral::Workflow task property
