Nit: I think you can drop this clause: "The policy will be applied in its
entirety, without exception." is probably clear enough.

+    // the policy will be transferred/applied in its entirety.
+    m_universalAccess = policyOverrides.grantUniversalAccess();
+    m_enforceFilePathSeparation = policyOverrides.enforceFilePathSeparation();
+}
