Hi Greg,

I still don't understand what's the intended purpose of the draft. Does it change/update any procedures in 5880/5883 and if so could you please clarify why and how?
   
Regards,
Reshad.

    The IPR disclosure and the licensing terms are clear.
    
    The patent is still pending.  The draft is against procedures largely
    specified in 5880, 5883, and 5884.  Presumably IPR has been filed because
    you're saying that you're doing something new against these documents.

    I don't understand.
    
    Basically, 5880, 5884 leave demand as an option.  It's built into the specs.
    It's unclear what you're suggesting being changed.
