Thanks for comments. 
In DRM specification, the Request message will contain the signature of the
Request entity. 
I think better to give a concise introduction of this point.
Here I am not quite clear of your said " If device B's rights are to be
added to device A's authorization", can you pls give me a use case to help
me understand it.
Thank you.
Zhipeng

        I don't see any signature applied by Proxy Device B, so what is the
point of its certificate in this protocol?  I am not questioning the
function of the proxy itself, just of its certificate.  If device B's rights
are to be added to device A's authorization, should it not authenticate
itself at some point, perhaps through a countersignature?

Hi Aram,
Nice to hear you.
Are you going to Sweden ?
If you can help me gathering more comments in the meeting, that will be 
exactly wonderful for me.
Thank you.

Hi Zhipeng,

Interesting draft RFC. Here are a few minor comments:

“Trusty” is not a word. I believe what you want to say is “trusted 
relationship”. 
In section 5.1 you are using the binary format description language we 
defined in OMA DRM but you have not explained how it is used.

Take care,
Aram
