This enumerated value ("policyOwner") indicates whether the SAS-expander definition's settings are owned locally by this object or inherited from a policy defined higher up the org tree, per the CucsPolicyPolicyOwner type. This matters because if the value shows the definition is policy-owned rather than locally owned, an admin who wants to change how UCS Manager reports this expander variant needs to edit the shared catalog policy rather than the individual object, or the change will be overwritten. For example, a value of "policy" would tell the admin the SAS expander definition is centrally managed and any local edits attempted through the object itself would not stick.
