The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
The generated payload is incomplete because one or more ADMX element values were not supplied: L_showassociatedwebpage45, L_urladdressofassociatedwebpage46, L_turnoffinternetexplorersecuritychecksforthiswebpage47
