IMO, part 2 above is an absurd question, since the W3C does not build user
agents and does not control what goes into a user agent. If you want to be
serious about this question, then first you must precisely define what is
in scope in the phrase "to interoperate". In the discussion at hand, I
would expect the CDM interface and a Clearkey CDM to be in scope (since
they are proposed to be specified by the W3C) and other CDMs to be out of
scope (since they would not be specified by the W3C). However, I guess that
you consider CDMs not defined by the W3C to be in scope, at least as far as
the W3C is concerned. That's sort of like asking whether specific uses of
XML are in scope for RF implementation since W3C defines XML as RF
technology. We know there are many uses of XML for which patents have been
granted (I'm not judging the appropriateness of this, it just happens), but
do we wish to constrain users of XML to only use it in RF contexts? You
seem to be arguing that W3C adopt a GPL like regime which would refuse to
permit use of W3C technologies in non-RF contexts. If that is what you are
arguing, I expect that you represent a small minority of participants in
