Thank you for informing us of your work.

The introduction says, "it is not expected that a device will use this
exchange format." Thus, I do not think it applies to any of the work we are
doing. However, it is good to see parallel efforts to improve the
interoperability of different content protection systems.

If DASH-IF were to consider extending something like this to the client (UA
or CDM), I would be concerned about the use of XML due to the size,
complexity, and security implications.

Regards,
David
