>From v0.1:
It has been proposed that needkey be a simple event. In this case, it would not
provide any indication of the key that is needed and the application would need
to call generateKeyRequest() to get an appropriate message or identifier,
including for the Clear Key case. Such a change assumes that the consistent
flow option is selected. See this example for an illustration of the impact of
this change.
(Because sessionId is not included in needkey and is not generated until
generateKeyRequest() generates a keymessage event, this cange would not result
in the loss of any correlation. See Session Correlation for a discussion of the
general lack of correlation.)


See
http://dvcs.w3.org/hg/html-media/raw-file/tip/encrypted-media/encrypted-media.html#issue-needkey-simple-event-example
for the possible impact of this and other proposed changes.
