Glenn,

thanks for the answer, but I do believe that the EME draft is to be a
standard at the end, so I would expect to have the CDM standardized as
well as it is part of the EME system.

I won't mind if this thread can be the start of standardizing the CDM
which is in my view essential to have conformance across browsers and to
allow any DRM system to be used across all of them.
