// three values: |ALLOW|, |DENY|, or |IGNORE|. If a Rule returns |ALLOW|, it
// means that the policy it represents would allow access to the requested path.
// If |DENY| is returned, then the rule is explicitly denying access to the
// resource. |IGNORE| means that the Rule makes no decision one way or another.
