Section: "Global policy packages".
The guide states: "When a global policy package is assigned to an ADOM
the policies in the global policy package are inherited by the ADOM. The policies are read-only in the ADOM." This directly confirms that the customer administrator cannot edit the inherited global policies.

Section: "Global policy packages".
This section details the structure: "The global policy package contains two sections: Header policies and Footer policies. Header policies are inserted before the ADOM policies
and Footer policies are inserted after the ADOM policies." This illustrates the hierarchy where the ADOM administrator works between the unchangeable global policies.

Section: "Administrative Domains (ADOMs)".
The documentation explains the purpose of ADOMs: "ADOMs enable the superadmin to create groupings of devices for administrators to monitor and manage." This reinforces the principle of administrative segregation
where a customer administrator's scope is intentionally limited to their assigned ADOM.
