--- Comment #10 from David Dorwin <ddorwin@google.com> ---
As discussed at TPAC, there are two issues:
1) Should we expose key-system specific values in a way that applications could
switch on? (And how can we prevent/discourage that?)
2) If so, how should we expose them? "Errors" related to EME can include
HTMLMediaElement decode errors (MEDIA_ERR_DECODE), rejected promises, and
unusable keys (bug 26372). If system codes apply to all, how should we report
them. One argument is that any EME-related error that might cause playback to
stop probably results in a key not being usable. Thus, the solution for the
first category might be reported via the last one.

Jerry to drive resolution for #1 then propose something for #2.
