46 * A policy is the fundamental business-related configuration of Aquarium.
47 * Policies change over the course of time. The underlying representation must be immutable.
49 * TODO: The following sentence will self-destruct at most after 200 commits.
50 * This model supersedes the original DSLPolicy, after changes in requirements and some thoughts on simplicity.
