# Policy CSP - ADMX_NCSI
>[!TIP]
> These are ADMX-backed policies and require a special SyncML format to enable or disable. For details, see [Understanding ADMX-backed policies](./understanding-admx-backed-policies.md).
>
> You must specify the data type in the SyncML as <Format>chr</Format>. For an example SyncML, refer to [Enabling a policy](./understanding-admx-backed-policies.md#enabling-a-policy).
>
> The payload of the SyncML must be XML-encoded; for this XML encoding, there are a variety of online encoders that you can use. To avoid encoding the payload, you can use CDATA if your MDM supports it. For more information, see [CDATA Sections](http://www.w3.org/TR/REC-xml/#sec-cdata-sect).
