Definition of targets for Policies from Section 3.8.6.1 of Version 1.3 of the TOSCA specification.
Support for targets in the Policy Framework
The TOSCA specification is silent on how targets, should be interpreted. Therefore the Policy Framework will allow the user to specify what way the targets should be treated for each PolicyType or Policy on which targets are specified. This will be achieved by asking the user to specify a XACML policy for each PolicyType or Policy on which targets have been specified.
