            Bug ID: 25271
           Summary: Key Session description of key usage is ambiguous
           Product: HTML WG
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Encrypted Media Extensions
          Assignee: adrianba@microsoft.com
          Reporter: steele@adobe.com

In this section
(https://dvcs.w3.org/hg/html-media/raw-file/tip/encrypted-media/encrypted-media.html#key-session)
this text "Other MediaKeys objects, CDM instances, and media elements may not
access the key session or use its key(s)." is ambiguous. 

You could interpret this to mean that two content streams that share the same
key cannot be played at the same time. I believe what is meant here is that the
each media element must have it's own key session, not sharing a common key
session. I don't believe the intent is that the duplicate keys cannot be used
in different key sessions.
