You must specify the data type in the SyncML as <Format>chr</Format>. For details, see [Understanding ADMX-backed policies](./understanding-admx-backed-policies.md). > > 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.
