+    description: From 'http://docs.oasis-open.org/tosca/TOSCA/v1.0/os/TOSCA-v1.0-os.html#_Toc356403653': Non-functional behavior or quality-of-services are defined in TOSCA by means of policies. A Policy can express such diverse things like monitoring behavior, payment conditions, scalability, or continuous availability.
+    A Node Template can be associated with a set of Policies collectively expressing the non-functional behavior or quality-of-services that each instance of the Node Template will expose. Each Policy specifies the actual properties of the non-functional behavior, like the concrete payment information (payment period, currency, amount etc) about the individual instances of the Node Template.
+    Policy Templates provide actual values of properties of the types defined by Policy Types. For example, a Policy Template for monthly payments for US customers will set the “payment period” property to “monthly” and the “currency” property to “US$”, leaving the “amount” property open. The “amount” property will be set when the corresponding Policy Template is used for a Policy within a Node Template. Thus, a Policy Template defines the invariant properties of a Policy, while the Policy sets the variant properties resulting from the actual usage of a Policy Template in a Node Template.
