Specifies the DRM client that cannot access content. Specified by DRM client version and platform.
Example use case: In the event of a security breach, a newer version of the DRM client can be specified as the minimum version required for license acquisition and content playback. The license server checks that the DRM client making the license request meets the version requirements before issuing a license. The DRM client also checks the DRM version in the license before playing content. This client check is required in the case of domains where a license may be transferred to another machine.
A DRM client version may be identified by the attributes specified in the following table:
