I can't speak for vendors, but I hope it is not going to raise objections,  
as it does not involve components that are undefined or cannot be freely  
licensed. As it stands, despite having quite short spec, it's fully  

It also works without JavaScript, supports more than just video and is  
even HTML-agnostic, so I think that's an attractive alternative to the  
ClearKey system of the Encrypted Media proposal, so it has changes for  
adoption, assuming vendors are interested a clearkey solution in the first

Drafts do not represent consensus. They are only a base for the discussion.

We've been discussing a specification that only defines a ClearKey  
encryption for a while now, and this particular solution has been drafted  
in response to use-cases outlined by Mark Watson.

If this solution has weaknesses or is not sufficient for cases ClearKey  
was intended for, then of course please speak up about those issues —  
that's the right place and time to do it.
