Pull request overview
This PR updates the MediaKeySession Interface portion of the EME ReSpec document to rephrase previously-passive conformance requirements into affirmative statements that name the responsible actor (e.g., the user agent or the CDM), aligning with the conformance-class clarity work discussed in #531 and as part of #595.
Changes:
- Attributes MediaKeySession lifecycle/concurrency requirements to the user agent (e.g., monitoring CDM state changes, session object lifetime/event delivery).
- Attributes session ID, session data isolation, persistence, and message-content requirements to the CDM (e.g., per-origin uniqueness, storage isolation, identifier restrictions).
- Editorially refactors several MUST/MUST NOT statements to explicitly name the actor while preserving intent.
