# HealthAttestation DDF


This topic shows the OMA DM device description framework (DDF) for the **HealthAttestation** configuration service provider. DDF files are used only with OMA DM provisioning XML.

Looking for the DDF XML files? See [CSP DDF files download](configuration-service-provider-reference.md#csp-ddf-files-download).

The XML below is the current version for this CSP.
