Devices may be revoked by the provisioning server resulting in an
error message contained within the provisioning response. The CDM
core currently returns an error, but the CE CDM would map this to
an kUnexpectedError, which does not provide the information to the
CE client to react. This situation is not immediately recoverable,
but may provide certain apps to use a different DRM plugin if they
support such a thing.
Documentation and tests are needed.
