Is it possible given URI with .xml extensions by Redfish

Hi,
I'm able to see below content via GET /redfish/v1/$metadata:

<edmx:Reference Uri="/redfish/v1/JsonSchemas/AMIManager_v1.xml">

<edmx:Include Namespace="AMIManager"/>

<edmx:Include Namespace="AMIManager.v1_0_0"/>

</edmx:Reference>

<edmx:Reference Uri="/redfish/v1/JsonSchemas/AMIBIOSInventoryCRC_v1.xml">

<edmx:Include Namespace="AMIBIOSInventoryCRC"/>

<edmx:Include Namespace="AMIBIOSInventoryCRC.v1_0_0"/>

</edmx:Reference>

<edmx:Reference Uri="/redfish/v1/JsonSchemas/InventoryCRC_v1.xml">

<edmx:Include Namespace="InventoryCRC"/>

<edmx:Include Namespace="InventoryCRC.v1_0_0"/>

</edmx:Reference>


But I given URI with .xml extension like GET /redfish/v1/JsonSchemas/AMIBIOSInventoryCRC_v1.xml will return 403 forbidden error.
Why the URI link exist in $metadata but cannot GET it via Redfish?


Thanks,
Felix
