            Bug ID: 23866
           Summary: Remove section 4.3. Addition to Media Element Load
                    Algorithm
           Product: HTML WG
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Encrypted Media Extensions
          Assignee: adrianba@microsoft.com

Section 4.3. Addition to Media Element Load Algorithm [1] has a single purpose:
"Clear the keys attribute for this media element." This is left over from the
original spec [2], which said to "Clear all cached keys for this media
element." At that time, it was important to be able to reset the key state of
the media element. However, now, the state can be reset by removing/replacing
the attached MediaKeys.

Therefore, I think we should remove this section. This simplifies things (no
longer modifying an external algorithm) and gives applications more flexibility
(the src attribute can be changed without having to call setMediaKeys() each
time.
